Here are 96 exciting levels waiting for you to solve :lix-cool: or backroute :lix-evil:! The pack already comes with the latest Lix version (http://www.lemmingsforums.net/index.php?topic=2815.0), so no need to download anything further.

Stunning visuals! Compared with Lemmings tilesets, some Lix tiles lack powerful 3D-lighting, yet you have crafted great images with the Lix tiles. Some levels even thrive on the flat design. Study in Scarlet shows masterful tile grouping.

From playing the NL version at Icho's, I know about the quality in the easier half of the pack. These levels are already challenging. I'm looking forward to explore the other levels.

We can include this in the D Lix test versions, or maintain it as a separate download for now. It's your choice.

-- Simon

I had a look at almost all of the levels from Planet and Sun. Each level, I basically played for 10 minutes, and if I didn't make good progress I'd move on to some other one. Exceptions are the last two of Sun and Planet 5, 6 and 10 (either because I'd seen them before or because they looked too daunting).

I think some levels I backrouted pretty badly.
But quite a few I found excellent and great fun. Of the ones I solved Hope and Despair is my favourite one.

I'd like to write a bit more about some levels, but it's pretty late now and I probably won't have much time to play or write anytime soon, so I just want to get out what I have so far. But either way I've had a lot of fun so far and even the ones I haven't solved yet are quite intriguing.

Thanks for all the replays. Unfortunately most of them are backroutes, a lot of them introduced by subtle changes in the game mechanics of Lix compared to NeoLemmix and by slight inaccuracies when copying the terrain. In detail:

Spoiler

Fourtissimo: Glaring backroute.
Five do not survive: It seems that I have to remove the batter. Adding it to require less timing was probably not a good idea.
Construction zone: Backroute due to different digger behavior.
Tomb Raider: Backroute due to slight terrain changes.
Minimalistic Platforms: I already checked this approach, but appearently not in enough details - backroute.
Toy Ship: Slight variation of the intended solution.
Cubism: Again a glaring backroute due to subtly different terrain widths.
Death of a Working Lix: Backroute. I never even considered this approach and was simply fortunate in the NeoLemmix version.
Choir of the Mad: That is a very embarrassing backroute :lix-blush:
Canonballs: The left-hand side is totally fine, but I will block the way you did the right-hand side.
No matter what I try: Very interesting solution and completely different to mine. I have not yet decided what to do with it.
Minor Obstacles: This is truly embarrassing, because I gave you floaters where you should have none... :lix-gasp:
Marble Temple: Again a backroute introduced by subtle terrain changes combined with less strict terrain checks for builders.
Chinese Lemmings: Essentially the intended solution.
Ugly Bricks: This is an open-ended level, but your solution feels slightly too easy...

Hope and Despair: Intended.
Icy Smell of Steel: Glaring backroute to both the Lix and the NeoLemmix version. Given that a lot of people found other much harder (and acceptable) solutions this is quite surprising.
Broken Symmetry: Again subtle changes in the terrain made this backroute possible.
Woodworms: Intended.
Lament of Innocence: Acceptable alternative solution, that was already found for the NeoLemmix version.
Divide & Conquer: Backroute, but given the huge amount of backroutes for the NeoLemmix version, this is not surprising.
Advanced Earth Cube: Backroute, due to a slightly thinner gap to bridge.
Builders Prohibited: Another backroute, this time caused by my changes to allow for fixed SI.
Heart for Lix: I tried this backrouty approach, but couldn't make it work myself. Thanks for showing my that it is still possible.
Edge of Death: Same here.
Magic Wings: Oh, this is very bad! Now I have to adapt all my levels with one-way-gadgets...
Fall and Never Live: Totally my fault. This backroute was already found for NeoLemmix, but only after I converted the level. Then I forgot to fix the Lix version.

Here is version 1.1 of NepsterLix with all backroutes found by geoo and Simon fixed.

Here is version 1.2 with further fixes for backroutes found by Ramon and IchoTolot. Moreover imploder counts were reduced when they could never be part of a solution.

Version 1.3 with fixes for backroutes found by Simon.

Version 1.4 fixes more backroutes Simon found in the Moon and Sun rank.

Version 1.5 fixes some backroutes by geoo and Simon. Some levels in the last two ranks got reordered.

And already version 1.6 fixing 14 backroutes that Simon already found a while ago, but only sent to me a few days ago.

NepsterLix 1.6 is now part of the main D Lix download (http://www.lixgame.com). All levels are proven solvable. I'll continue to watch this thread for updates.

-- Simon

See the first post for version 1.7 of NepsterLix. If you are using a lix version of 0.7 or newer, you should update this pack.
Main changes:
- New level "Haunted Walls".
- Moved level "We all fly down" to Outtakes, because the new digger mechanics make the solution very fiddly.
- Moved "Construction Zone" and "Woodworms" a rank down, to make place for the new level.
- References to oriental and occult pieces point to the new piece names (thanks to Simon for fixing that).
- The three levels in the oriental style ("Don't feed the frogs!", "Travelling lix" and "Chinese Lix") are recreated  with the new pieces.
- Backroute fix to "Blockers forever".

I removed the download option of this pack from the first post, as Lix now ships with the latest version of the pack and the version in this thread wasn't up-to-date anyway.

I still greatly appreciate any feedback in this thread, though.

Attached solutions to 19 out of 20 levels of the Moon rank. Most of them are done in 0.9.2 and some in 0.6.x but the ones of 0.6.x attached should work in 0.9.x as well.

It was already very hard for me despite being the first rank.

Some remarks

Apart form "Study in Scarlet", which I haven't solved yet, I found actually the first two levels quite hard.

I liked  "Another Miner Problem", "Earth Cube", "Blockers forever", "White Wonder" and "Construction Zone".

I'm not sure if I solved "Colored Cube" intended since it is in a particular way precise but everthing worked out.
For "The Prisoners" I saved the batter and climber, so I don't know if it was the way to go.

If "Horror Ping-Pong" is fully intended then it's quite precise since I only got it with early basher assignment.
If "Don't feed the frogs!" is intended then it's very bruteforcy. It's a nice trick to close the imploder gap but you have to go for it in the hope that it works out.
If "Direct Misdirection" is basically intended then it's quite special what one has to do. I probably did it overprecisely but nevertheless.

In "Maze-Lix" it was hard to coordinate all actions. I at first did multiple replays and copied them together but the attached replay is a reproduction of it in one go. As I knew a way it wasn't that bad anymore.

Thanks for the replays. Technically the first rank is the "5-of-all" rank, and at least its first levels are easy intoduction levels. But I agree that the Moon rank is already rather difficult. I am just terrible at creating easy levels. ;)

Remarks on your solutions

All solutions I don't comment on are absolutely intended.
Another Miner Problem: Backroute, even though you liked it.
Colored Boxes: Completely different from the intended route, but this level is incredibly nasty to fix, so I might just accept your solution as an alternative one.
Blockers Forever: Accepted alternative solution.
You need Blockers this time: Backroute.
Lix Playground: Backroute. While this level has a lot of different solutions, yours misses the key characteristic of all others.
Jump in the Ring: Interesting alternative solution. Haven't seen this one before.
Horror Ping-Pong: Backroute.
Prisoners: Not one of the two acceptable solutions. So I really don't know whether I want to keep it or not.
White Wonder: While I am glad that you liked that level, your solution is a 100% backroute.
Construction Zone: Same here.
Don't feed the frogs: The intended way is far less precise. But your solution seems nevertheless close enough that I will keep it. I might raise the SI to make it easier to execute your solution, though.
Direct Misdirection: No, that is a backroute. If I had intended that route, then I would have made the execution far less precise.
Miner Preservation Society: Shame on me for not seeing this backroute.

Thanks for the feedback.

I played through the 5-of-all rank and yeah, that are the easier levels. Sorry, I didn't realize that this was the lowest rank. I thought it was something extra due to its different naming.

Some remarks

"Stopping Stones" seemed a bit too many stones for me.
"A Small Step for Lixkind" and "Lots of Small Tasks" hit my weakness of not being good at imagining a level in advance. I actually generally like the small-task-concept but it was just too much for me to manage.
It's kind of uncanny that the hell route in "Paradise or Hell?" seemed to be the easier one to me.

There were some fun levels in between.

Maybe it's obvious but only one question concerning the Outtakes:
Are the times given in the name of some of the levels meant as time limits?

Quote from: Forestidia86 on December 16, 2017, 11:10:17 AM
Are the times given in the name of some of the levels meant as time limits?

Yes, they have been time limits in C++-Lix. As D-Lix no longer supports time limits, these levels got moved to the Outtakes rank and the time limit mentioned in the level title.

Old C++ Lix had the time limit run for 4 seconds, then spawned the first lix.
Newer C++ Lix had the time limit run for 2 seconds, then spawned the first lix.
The first lix has always spawned at phyu 60.
One second has always been 15 phyus.

Since NepsterLix was well-maintained near the end of C++ Lix's life, assume 2 seconds before spawn. Then D Lix would time-out a solution at
phyu ((time limit in seconds) * 15 (phyus/second) - 30). For one minute, this is phyu 870.
phyu ((time limit in seconds) * 15 (phyus/second) + 30). For one minute, this is phyu 930.

Shouldn't the 60 phyus be counted in the calculation for D-Lix or do I have a thinking error?

Yes, I should compute +30 (or +60-30) instead of -30. Fixed in the post.

-- Simon

So since we put the effort in the calculation, some solutions to Outtakes levels attached, including the three time limit ones.
They should all be (barely) be within:

"Just a quickie" has 30s, i.e. 480 phuys in D-Lix
verifier.txt says 411 phyus for saving the last required lix.

"It's hero time again!" has 60s, i.e. 930 phyus in D-Lix
verifier.txt says 911 phyus for saving the last required lix.

"Time Out" has 180s, i.e. 2730 phyus in D-Lix
verifier.txt says 2710 phyus for saving the last required lix.

Edit: Level file to "Time Out" says actually 210s but title says 3min, I just took the title at the word.

I finally found a solution to "Study in Scarlet". I don't know what to say.

This is identical to my solution. The NL version had a second route that doesn't work in Lix. The Lix version is harder and could be ranked higher.

-- Simon

Lix 0.9.7 doesn't replace tiles like `moon.D' to `moon' anymore. Decoration was removed a year ago and I'd like to remove the backwards compatibility. 3 levels of NepsterLix need these minimal changes, all stay solvable with the replays in the proof collection.

Here's a patch against the NepsterLix git repo. To turn it into a commit:
git am 0001-replace-deco-with-solid-terrain.patch

-- Simon

Sorry, that I'm just posting a single solution, but is that intended ("Fourtissimo", v.0.9.7)?
That felt remarkably easy considering what the Moon-difficulty threw at me.

Regarding your replays:
Fourtissimo: Yes, this is a backroute.
A Move on the Roof: Backroute, but because this is a level in Outtakes, I won't fix it.
Poor Wee Creatures - Twin Edition: Slight backroute, but again I won't fix it.
It's hero time again! - 1min: Nice alternative solution. :thumbsup:
Just a quickie - 30sec: Another nice alternative solution.
Time Out - 3min: That's a simpler solution than mine, but much tighter on the time.

@Simon: Haven't gotten around to apply your patch, but will do so eventually.

Thanks for your feedback.

I have attached a set of another 5 solutions to the Planet rank. Unfortunately all feel backrouty.

Some remarks

"Slow down, Walkers!" - I thought a bit too complicated in the beginning. The more straightforward solution worked. Though it had kind of some trick to it then.
"Five do not Survive" - Hm, felt somehow easy.
"A Stroll on the Lawn" - Hm, I just abused the lower save requirement.
"On the Toy Ship" - This was the hardest of the 5 solutions for me. But it felt somehow hacky-precise what I did.
"Cubism" - This solution felt somehow peculiar and it was precise as well.

I solved 5 further Planet levels.

Some remarks

"Minimalistic Platforms" felt like the level solved itself.
"Choir of the Mad": What I did happened to work out somehow.
"Minor Obstacles": I have two slightly different solutions for the level but the second one is much more precise.
"The Marble Temple": This level felt quite easy. The only thing to take care of was the order of actions so that the climber is saved as well.
"Chinese Lix": I doubt that the solution is intended since I just tried around until the timing worked out. I even did an empty basher assignment to hold one lix up.

Solved 5 Sun levels.

Some remarks

"Lament of Innocence": Was a nice level. How I solved it relied on two main tricks and wasn't extremely hard.
"Three Little Lix": Not sure if the pickaxe turn move was intended. But managing the timing and distances between the lix seems the tough part of the level.
"Advanced Earth Cube": How I solved it, the solution seems a bit out-of-the-box at one point. Managing the destructive skills is the tough part here.
"Magic Wings": The trick in the end felt a bit hackish but could very well be intended.
"Fall and Never Live": It feels a bit backrouty. Although these could very well be the main tricks of level and the rest is just distraction.

Solved 4 further levels of the pack.

Concerning "The Shortcut"

My solution is peculiar but fits the title.

Concerning "Dawn in Lixtown"+"A Day in Lixtown"

Nice interesting levels and good that they needed different solutions.

Concerning "Ticket to Hell"

This was about managing the ressources. I first didn't realize that they won't walk into the fire at the top.

Edit:

To "A Night in Lixtown"

There basically my Dawn in Lixtown solution works, only with a bit different timing due to different SI and I cancel the miner with a jumper.

Thanks a lot for the replays and the feedback. I already feel bad for not replaying earlier.

Slow down, Walkers: I don't know how I missed this backroute.
Five do not survive: Backroute, that might not have been possible until the digger changed.
Stroll on the Lawn: Alternative solution, which is ok.
Minimalistic platforms: Great, then my efforts to make the level easy to execute paid off. Intended solution.
On the Toy Ship: Basically the intended solution. You simplified one small detail and traded it for some precision.
Cubism: This level is backroute-hell, and this is just one more of them...
Choir of the Mad: I already put so many fire traps there, and you still got around them. Backroute.
Minor Obstacles: Cool alternative solutions! :thumbsup:
Chinese Lix: Yes, the intended solution is completely different. But I like your approach, even though I worry that allowing this leads to too much fiddling around. I am not yet sure, whether and how to fix this level.

Lament of Innocence: Known and acceptable alternative solution. You got the main ideas.
Three little Lix: Backroute.
Advanced Earth Cube: There are some good ideas in there, but the beginning is just backroutish.
On Magic Wings: Apart from the end, it resembles the intended solution. But that end has to be fixed.
Fall and Never Live: Yes, this is backrouty.

Dawn in Lixtown (and Night): Backroute.
A Day in Lixtown: This should be the solution for another version of Lixtown.
Ticket to Hell: Backroute, because the lemmings should walk into the fire at the top. Not sure what I thought when putting terrain there...

The Shortcut: Not intended, but the level is bad anyway, so no big deal.

Thanks for the feedback.

Attached a backroute for "Minimalistic Platforms".

Just some replays to three more levels. (Moonshine Trio, Sacrifice of a Climbing Lix and 2 solutions to Dunes)

Some remarks

Moonshine Trio: This actually feels intended, although I saved one blocker. Looks at first like there are many possibilities to try but in the end it's not that bad.
Sacrifice of a Climbing Lix: My solution is likely a backroute: I saved the climber, saved 27 instead of 20 and had plenty of skills left. A variant of this works in Neolemmix, although there you have to avoid traps that aren't in this Lix variant, but you have enough skills for it, and the setup for one step is harder due to different blocker physics, which are more lenient for bypassing than in Lix.
Dunes: I have two solutions there one of which feels intended and works in Neolemmix as well. The other solution abuses the runner in combination with precise basher assignment, which to a certain extent triviliazes the level.

I've solved the Planet level "No matter what you try... " and Final Frustration.

 To No matter what you try...

Everything just worked out together without that much precision than I expected for my route.

 To Final Frustration

Than level has some nasty parts you sometimes don't see in the beginning. If you make a mistake at an early stage you can redo everything. It nevertheless stayed always interesting though exhausting to deal with this level. The toughest hatch to deal with was the lowest hatch. The right side was a bit easier to deal with generally.

I've solved "The Deadly Rooms of Lix".

Spoiler

My solution felt much too easy for the rank.

I've solved House of the Mad Trickster.

Spoiler

It's peculiar but uses most of the skills.

Edit: I've solved A Heart for Lix as well.

Spoiler

Not sure if it's intended that way; parts of it seem fitting, other parts just like an abuse of the amount of builders.

I've solved "The Icy Smell of Steel" and "Oh, to be a Squirrel".

Spoiler

I think I have a heavy backroute to "The Icy Smell of Steel".
I used by far not all of the climbers in "Oh, to be a Squirrel" but had some route.

Edit: I've solved On the Edge of Death.

Spoiler

My solution was very straightforward.

I've looked through the Black Hole rank, for which levels I have a quick idea.
I've solved:

Gray Walls

My solution feels intended but was not that tough.

The Rule of the One

I totally lucked this level out what was funny for me. I liked the general concept of the level.

Cross the Red Line

Was a short concise level. It was not that hard to find a solution.

A Sunny Day in April

Was interesting to puzzle a way for the crowd together. Feels like there are some backroutish parts.

I've looked through the rest of the Sun rank the same way and solved three further levels.

Hope and Despair

Was a bit trickier to keep the two apart in a working way but the level doesn't leave that much possibilities.

Broken Symmetry

I went for the right route. Was tight on timing for making the route.

OddBox

Interesting to keep the crowd away from the worker.

I've solved three further Planet levels.

Death of a working Lix

That level is tough and tightly timed as I solved it.

Canonballs in the Air

That was about puzzling together a route. Timing plays a role here and I used an unelegant "trick" to make it work out.

Ugly Bricks

Not sure if it's intended that way since I only used one blocker and really abused the amount of stairs available to keep up lix.

Two solutions to One Minute of Action.

Spoiler

The first one is likely a backroute since it just abuses the abundance of skills for delay. The other one is a bit less blatant but the level seems to offer many possibilities to solve due to the abundance of certain skills and low amount of lix.

Here's one more solution for One Minute of Action.

-- Simon

A solution to "Another Generic Title".
It doesn't feel fully intended and has one (not necessary) "swag" move.

I've solved "Builders Prohibited".

Spoiler

I had one skill left but the main approach seemed intended.

Without even having looked at your solution: Having one or two skills left over is fine. There are actually several solutions to that level.

I solved thin layers (with a bit of discussion with Simon).
I needed quite some time and saved one more than required.

I think I have another backroute to "Choir of the Mad".

I think I have the intended route.

-- Simon

I finally started fixing all the backroutes:
1) Choir of the Mad: All solutions so far have been backroutes (some of them huge ones, some a lot closer to the intended one).
2) Fourtissimo: Backroute by Forestidia (no big surprise)
3) Hope and Despair: Backroute by Forestidia (again no big surprise)
4) Gray Walls: Backroute Forestidia - the old time limit on that level would easily have prevented this one.
5) Moonshine Trio: Backroute by Forestidia - it misses the main idea.
6) Another Generic Title: Backroute by Forestidia - I already got the very same backroute in NeoLemmix, but forgot to fix it here.
7) Minimalistic Platforms: Removed the one backroute by Forestidia, the intended solution is of course kept.

Likely a backroute to "Bowl of Pillars".

Solved "No added Colors and Lix".

Spoiler

Not sure if it's intended that ways since I had the floater left. The route is rather a counterintuitive one.

Some solutions, probably some backroutes as well.

My solution to "Miner Preservation Society"

Silken's solution to Miner Preservation Society is a backroute. I've fixed it now.

Changes to NepsterLix in Lix 0.10.30, which released today:

• Introducing Climbers: Fix typo in the title: Introdicing -> Introducing.
• Miner Preservation Society: Add some ceiling terrain. This fixes Silken's backroute from the previous post. This moves the left hatch leftward by 16 pixels (from x = 16 to x = 0) to look nicer. This broke the covering replay. I've re-covered the level.
• Cannonballs in the Air: Fix typo in title and filename: Canonballs -> Cannonballs.

---

Attached are my solutions to 5-of-all, Moon, and Planet. Many of the solutions in Moon and Planet are backroutes.

I've skipped Altruism and No Matter what I Try. These two were harder than the others in Planet. I haven't attempted Empty Walls yet. I'll continue with Empty Walls and the later ranks.

Lovely levels! My favorites: Construction Zone, Fourtissimo, Woodworms.

-- Simon

August 20, 2026 NepsterLix stream is over and I've managed to solve all of the 5-of-all rank and the first 6 levels of the Moon rank. My replays are attached! :thumbsup:

Colored Boxes and Blockers Forever appear to be backroutes, just like how I also backrouted the both of them in NepsterLems

I attempted Study in Scarlet and is a no solve. I remember struggling with the level in NepsterLems for a while as well before I finally solved it. The NL solution doesn't work at all for the NepsterLix pack, therefore the level is completely new to me in NepsterLix despite having played and solved the NL version of the level back in 2020.

Moon 2 level typo isn't fixed in my version of the pack despite Simon claiming it's fixed in his post above. edit: I know what happened. I copied over a levels folder from an older Lix directory on my hard drive and that's why I have the typo in the Moon 2 level title. However, the colon between "introducing" and "miners" is missing in the Moon 1 level title, and same thing with the Moon 2 level title missing the colon between "introducing" and "climbers."

Overall, NepsterLix feels many times harder than NepsterLems, even in the first rank of 5-of-all. Still, enjoyable challenges and it felt great to be playing Nepster's levels again after so long! :thumbsup: There have only been 2 levels so far that I don't recognize because they aren't in NepsterLems, "Such Clowns" and "Paradise or Hell?" I loved both of the new levels! :thumbsup:

Thanks to Simon and anyone else who caught my stream on very short notice and not spoiling any solutions for me as I've requested with my pinned chat message! :thumbsup: Yea, I definitely miss the NL implementation of the rewind to previous assignment unfortunately. I'm just used to it and honestly it feels more natural to me. It felt super awkward to need to also press the B key to step back a frame before assigning a skill after pressing the hotkey for rewind to previous assignment. In contrast, in NL I don't need to press the B key in addition to the rewind to previous assignment hotkey, I can simply click to assign the skill due to being on the correct frame (the "wrong" frame in NL due to being a frame earlier) so that I don't need to step a pixel further back with the B key too. 

Managed to solve Moon 7 - A Study in Scarlet now and wow, amazing solution! :thumbsup: Without having checked either of Forestidia's or Simon's solution, it sounds like mine is the exact same one as the both of theirs. Yes, agree completely with Simon that the level should be ranked higher! While this solution also works on the NepsterLems version, it is a far harder solution to discover than the other solution that's possible in NepsterLems but not in NepsterLix.

Next time I stream the pack I will show the solution to Moon 7 and then we carry onward and see how many more levels I can solve! :thumbsup:

Okay, the typo in "Introducing" is now clear, that came from old level files. What's best for the colon though? Lix 0.10.30 renamed "Introdicing: Miners" to "Introducing Miners" (fix typo, remove colon) to align it to the colon-less "Introducing Climbers". Now both levels lack a colon.

Do both of these two have a colon in NL NepsterLems?

Well done on Study in Scarlet! I haven't touched the ordering/ranking yet. I'd like to revisit this with you when you're further through NepsterLix. You'll then have experience of both NepsterLems and NepsterLix. We'll have a clearer picture before be break the equal orders between these two.

Colored Boxes: Maybe a backroute, hard to tell. Several skills left over, but about as hard as the route in Nepster's reference replay.

Blockers Forever: Backroute. I don't see an easy fix.

Lix UI: I'll continue this in a separate thread in the future.

Yea, both level titles contain a colon in NL NepsterLems.

Agree that we can leave the level ordering untouched for now until I get through all of NepsterLix

August 24, 2026 stream is over, and I show the solution to Moon 7, solved the remaining 13 levels of the Moon rank, and the first two levels of the Planet rank! :thumbsup: Replays attached.

The new levels to me were Moon 8 - You Need Blockers This Time, Moon 12 - The Prisoners, Moon 14 - White Wonder, Moon 18 - Direct Misdirection, and both Planet levels, Planet 1 - Fourtissimo and Planet 2 - Slow Down, Walkers!. The Prisoners and Fourtissimo were my favorites! :thumbsup: Though I'm not sure if my solution for the latter is intended. Also, I heard in Icho's and Simon's NepsterLix stream that it was one of the levels that Simon didn't solve, but I only watched the first minute or so of it. I will check it out! At the same time, it's from 2016 or so, but even then, should be a nice, entertaining watch! Not sure if Planet 2 is intended as well, though only one part of my solution feels a bit hackish.

Both Moon 14 - White Wonder and Moon 18 - Direction Misdirection seem to be backroutes.

Moon 19 - Miner Preservation Society Recently got backroute fixed, and IIRC this solution I found is the exact same one I use in NepsterLems.

Moon 15 - Construction Zone Here I remember abusing the digger on the NepsterLems version to cheese the level :laugh: Seems completely solid here for NepsterLix. Great level! :thumbsup: 

Moon 11 - Horror Ping-Pong and Moon 16 - Don't Feed The Frogs! are both in NepsterLems as well, albeit slightly different, since for the former has a runner skill in addition to the same skills in NepsterLems, while the latter has the platformers all replaced with builders. From memory, I use a timing based solution for the latter in NepsterLems thanks to how you can fiddle with the RR during gameplay and also with the differing platformer vs builder mechanics between the Lix and NL engines.

Moon 13 - 50% is not enough is Planet 13 in NepsterLems and I remember using an extremely heavy timing based solution in the NL version of the pack. Doesn't seem to work here in NepsterLix as you cannot mess with the RR/VSI during gameplay. It was also my very first major roadblock of Nepsterlems, as well as the level that caused me to quit the NepsterLems pack for a while before coming back to it much later in the future back in 2020. In fairness, I started playing NL content in 2019, for which NepsterLems was one of the very first level packs I played, along with Lemmings United, so I wasn't as experienced back then and hence roadblocks came up very often for me! :P

Can't wait to stream more of NepsterLix in the future. Looks like I'm just finding my stride and I haven't lost too much of my touch with Nepster's levels despite it being 3 years since I last played and solved all of NepsterLems! :laugh: :thumbsup:     

August 28, 2026 stream is over and I managed to solve 10 more levels of the Planet rank, one of which was Altruism, the level that Simon skipped :thumbsup: Replays attached :)

I also attempted Planet 13 - Choir of the Mad but was a no solve. I remember this level from Nepster's Return of the Tribes, the L2 level pack for Old Formats NL that Nepster never finished making, so it was just a matter of remembering the solution. There, it's remade in the L2 Medieval tileset. I wasn't able to remember the entire solution during the stream before I ended. I remember it involved some really clever use of the blocker, but what that is, I can't yet remember. The interesting thing is that I played through all the levels of the pack that Nepster made for Return of the Tribes last year. So, I apparently can remember solutions from 3-5 years ago but not from a year ago? It sure boggles the mind! :P At the same time, there's more, and that is I haven't spent anywhere near as much time on the Return of the Tribes levels as NepsterLems despite how the levels in the former are just as hard, if not harder, and it does feel a lot harder IMO.

Once I manage to solve Planet 13 offline I'll stream more of the pack. Still haven't figured it out yet, but I know the solution will come to me given time ;)

This time, the ones that look like backroutes are Tomb Raider and Cubism. At least I'm certain I don't recall solving Tomb Raider from NepsterLems like the way I did the NepsterLix version. I remember not taking a shortcut at all for the level in the NepsterLems pack and taking the long way around pretty much the entire level.

Both Altruism and Cubism were new to me, as they're not in NepsterLems. The rest of the levels I've played are from NepsterLems, so it was more or less a matter of trying to remember the solution I used in the latter. I remembered the solution to Five do not Survive incorrectly for a few minutes before it came back to my memory. I might had also been wrong about using an RR timing based solution in the NepsterLems version of the level. Any levels where I did abuse the RR manipulation in NL I had to come up with a somewhat new solution, though luckily they didn't need too much of a tweak from the solution I used.

Regarding Altruism, yes, absolutely agree that it's too difficult for its position. It really reminds me of Scrap the Builders from NepsterLems, and IIRC that level is Sun 7 in the latter, which is the rank after Planet and hence the 4th rank. Indeed, Altruism greatly resembles the layout of Scrap the Builders, and the feedback given for the latter is that it really feels more of a Black Hole rank level, and I absolutely agree there! Especially as both Icho and namida struggled with it. I did as well, and that was the next level of the pack that caused me to quit the NepsterLems pack for a while back in 2020, after I was finally successful in getting past my previous roadblock, Planet 13 - 50% is not Enough. Ultimately, when I finally did return to the NL pack, I ended up using a really overcomplicated solution that just barely works thanks to the fast triggering needles trap of the L1 Pillar set. Also, Altruism feels way harder than the NepsterLems version of the level!

Enjoying the pack as usual and can't wait to play the rest! :thumbsup: Great levels I remember them being, especially the new ones I haven't played because they're not in NepsterLems :thumbsup:     

Monday, August 31, 2026 stream is over, and I managed to solve Planet 13 offline, the remaining 7 levels of the Planet rank, and the first 8 levels of the Sun rank! :thumbsup: Replays attached.

Regarding Planet 13, turns out I was a big dumb dumb, as I apparently can't tell the difference between terrain and what I erroneously thought was water at the bottom the entire time! :forehead: Ok, the solution is slightly different to that in Nepster's Return of the Tribes, the latter which IMO has a far more clever use of the blocker in the level. Its use is somewhat clever in NepsterLix as well, just not as much :P Still, great level! :thumbsup:

Planet 15 - No Matter What I try... is new to me. It looks hard but it wasn't too bad at all, especially as my solution should be a backroute given the skills I had leftover. Hence, it's not as hard as it should be.

The remaining Planet rank levels are all familiar to me from NepsterLems, though I used slightly different solutions to Cannonballs in the Air, Minor Obstacles, and The Marble Temple. While solving Minor Obstacles, I learned a nuisance of bombing in a miner tunnel in Lix, where it makes an unsurmountable wall. I believe SuperLemmini has this as well, so it's not new to me, but rather, I don't think I knew about this Lix mechanic until this stream. At the same time, because the bomber holes are different depending on whether you use the flinging bomber or non-flinging one, it might be surmountable with the flinging bomber (Edit: tested it, and yup, it is).

For the Sun rank, only Haunted Walls was new to me. Hard one, though I eventually solved it and it's probably a slight backroute, but it's an excellent level despite that! :thumbsup:

I kind of dreaded playing Cliff Jumpers again in NepsterLix, as I remember the execution can be painful from NepsterLems. I checked my NL replay after I solved this level and turns out I more or less had the same solution, with the start done differently and done another thing differently to make execution a bit less painful and somewhat better skill management.

Lament of Innocence is a Sun rank level in Nepsterlix, whereas it's in the Black Hole rank (fifth and final rank) in NepsterLems, Black Hole 2 to be exact. I suppose its placement in NepsterLix is fine here, as IMO it honestly isn't too difficult of a level and not really much of a Black Hole level. On the other hand, I saw that Thin Layers is a Sun rank level in NepsterLix, whereas it's Black Hole 1 in NepsterLems. This is the level that was responsible for halting my progress in NepsterLems and hence prevented me from solving all of the pack for nearly 3 years! :devil: It is most definitely worthy of the Black Hole rank! From memory, Icho really had to convince Nepster to uprank Thin Layers to the Black Hole rank in NepsterLems. When this happened, Dunes in turn was downranked from Black Hole to Neutron Star, which I agree with, as Dunes is quite easy. I haven't played either Dunes or Thin Layers in NepsterLix yet, but I very likely will for Wednesday's stream (September 2, 2026). I'm simply pointing out the NepsterLems feedback on these two levels as best as I can recall them.

Can't wait to play more NepsterLix soon, and I continue to enjoy the pack very much! :thumbsup: 

Wednesday, September 2, 2026 stream is over, and I managed to solve the remaining 12 levels of the Sun rank, as well as the first 5 levels of the Black Hole rank! :thumbsup: Replays attached.

This time, only Dawn in Lixtown is new to me, as that one isn't in NepsterLems. It is also a level that wraps and is very small as indicated by the vertical gray lines. Despite the small level size, it still looks quite daunting, especially with the 1-of-everything skillset except for diggers, where you don't have any, along with two entrances and two exits. Overall, the level wasn't as hard as I expected, though that's because my solution is probably a backroute due to the skills I had left. Even then, it's still worthy of the Sun rank finisher position, especially as it has wrap. The level was a pretty enjoyable one to puzzle and work out! :thumbsup: I also love the various Lix sprites in the level! :)

The rest of the levels are familiar to me as they're all in NepsterLems as well. Except for Thin Layers, Mount Doom, and Fall and Never Live, which are in the Black Hole rank in NepsterLems, these levels are in the Neutron Star rank of NepsterLems, for which the Sun rank of NepsterLix is more or less the equivalent of (they're both the 4th rank out of 5 of their respective packs)

Some Sun Levels Feedback

A Ticket to Hell! - I remember my solution is slightly different in NepsterLems as I took advantage of a basher mechanic that's possible in NL but not in Lix

Spoiler

In NL, you can make a basher staircase by interrupting midstroke, but in Lix, she either removes none or all of the terrain at once, therefore making staircases with the basher is impossible in Lix.

Not only that, it took me a while to figure out the solution, as I couldn't remember the general idea for some time. Also, the NepsterLix level has a platformer, while NepsterLems only gives builders as it sticks to the classic 8 skills. Once I did figure it out, it was quite satisfying when it all fell into place! :thumbsup:

Oddbox - My solution is more or less the same as my NepsterLems solution, though here you have a runner and so I suppose it can be slightly easier to execute in NepsterLix. I think I remember abusing something in NL and hence it feels more of a backroute there than in NepsterLix.

Dunes Much harder here than in NepsterLems, though in the end I used the exact same general solution as the one in NepsterLems. It's pretty much a matter of allocating the runner skill to the right Lix in order for the timing to all work out. Also, as mentioned in the spoiler for A Ticket in Hell!, the level in NepsterLix is harder due to a basher mechanic that isn't possible in Lix but is in NepsterLems. Even then, I would agree that the NepsterLix isn't worthy of the Black Hole rank despite being a bit harder than the NepsterLems version.

Thin Layers - As mentioned in the stream, this was the level that was responsible for preventing my solving all of NepsterLems for almost 3 years, all because of one critical spot that I was pretty much blind to the whole time :forehead: See my video stream for the explanation, especially if you're not too bothered by spoilers :P Forgotten one part of the solution for a bit, but overall you can use the same solution here as in the NepsterLems version, except in the latter it's a bit easier to pull off since you can

Spoiler

adjust the RR during gameplay.

Also, this is Black Hole 1 in NepsterLems instead of a Sun rank level like in NepsterLix.

Mount Doom - Ok, there's a gap in the terrain that most definitely isn't there in the NepsterLems version. For some reason, I couldn't remember how to do the solution from there, and honestly I remember solving that level very quickly and was wondering, what the heck is this level doing in the Black Hole rank? It's quite easy for the final rank! I managed to figure out how I solved it in NepsterLems before I watched my video solution, so goodness knows why it didn't occur to me during the stream :forehead: Also, I at first didn't recognize that it has a version in NepsterLems, but I quickly caught on in the first few minutes. It's remade in the Dirt tileset and is Black Hole 10 there.

Spoiler

For whatever reason, it didn't occur to me to have the left digger go a bit lower than the digger on the right instead of cancel him before or at the same level of the digger on the right so that you can bash everyone out to the right, which gives the builder enough time to bridge the gaps and then to finish mining to the exit in time.

On the Edge of Death This level has a 1 minute time limit in NepsterLems and as such the solution I used here in NepsterLix wouldn't work because it would time out long before I can even finish the level. Also a bit easier to pull off in NepsterLems due to the spoiler above for Thin Layers.

Fall and Never Live - This level is in the Black Hole rank in NepsterLems. I remember using a really heavy timing solution there. Since that's not possible here in NepsterLix, it's probably just slightly easier as a result. Even then, I still don't find it easy in any way. It's one of the final 5 levels of NepsterLems and definitely one of the hardest of the pack. The bashing probably can be made easier, but to get it to work some precision was needed with some earlier parts of the level.

---

Some Black Hole Levels Feedback

A Heart for Lix - This level is in Return of the Tribes, the L2 pack for NL that Nepster never finished. I don't exactly remember the solution I used there, but I think I remember I used some extreme brute force to cheese the level. I might had done the same here as well, though it doesn't look too hackish or as brute forced.

Gray Walls - This one has a time limit in NepsterLems, though maybe my solution would finish on time here so all is fine.

The Rule of the One - Way more backroutable in NepsterLems due to how I used a heavy timing solution. The solution I used here in NepsterLix should be the intended way, as I tried other alternatives but couldn't get them to work, including trying to imitate the general heavy timing solution I used in NepsterLems.

A Bowl of Pillars - This one is a Neutron Star rank level in NepsterLems. I believe I use the exact same solution.

No added Colors and Lix Definitely a backroute, though I also use a really heavy timing solution in NepsterLems for this level that of course isn't required at all.

---

80/96 NepsterLix levels solved! Meaning, 16 more levels to go for the main part of the pack and then a final Outtakes rank are all that's left of the pack! :thumbsup:   

Wednesday, September 9, 2026 stream is over, and I solved 12 more levels of the Black Hole rank. Replays attached.

The new levels that aren't in NepsterLems are A Day in Lixtown, Cross the Red Line, and Very Derailed Level. The first one is a repeat of Dawn in Lixtown, which is the Sun rank finisher. The former is much harder as a result but it has an excellent solution and is one of my favorites! :thumbsup: I backrouted the original I believe.

Cross the Red Line should be a backroute, though I had another solution that would had worked except the climbers would climb a high wall and splat. I think it might had still been salvageable though with a minor tweak. I'll have to check. edit: Yup, it works, alternative replay included.

One Minute of Action is currently quite broken in NepsterLix, even without the 1 minute time limit like in NepsterLems. I do believe I backrouted the level more or less the exact same way like I did in NepsterLems.

Very Derailed Level is credited to Insane Steve/Nepster. Wow, really hard level, and in several of my attempts near the end I was fighting with a timing based solution that I couldn't pull off but that the level was actually solvable the entire time had I let it play out some more in the end :forehead: I don't know if my solution is intended, especially with the way

Spoiler

the basher was able to remove the thin wall as well so that you kill two birds with one stone here

The remaining 9 levels are in NepsterLems as well. I had to use a different solution for 9/11 in NepsterLix, as once again staircases aren't possible like they are in NL.

A Sunny Day in April felt easier here in NepsterLix than in NepsterLems for some reason. For the latter, it's definitely fitting for the Black Hole rank, as it's one of the hardest levels of the rank/pack IMO.

Mining the Rainbow is Mining Company in NepsterLems, is Black Hole 9 there, and is the level that namida stopped at in his LP of NepsterLems from back in I believe 2017 or so. This means he got about halfway through the final rank and had 13 levels left for NepsterLems. He has not gone back to solve the rest of the pack since. Yea, I can absolutely understand why namida got stumped on this level in NepsterLems. I too struggled with it from when I first played it in 2023. It too is definitely fitting for the Black Hole rank, as it's one of the hardest levels but one of the best of the pack IMO! :thumbsup: Here, I had trouble with the execution, which I don't remember having too much execution trouble with the level in NepsterLems.

HangLix is quite possibly the hardest level of the Black Hole rank, but only because it's very fiddly to get right no matter how you approach it. Like Icho, it's not one of my favorites of NepsterLems, though I largely have myself to blame for really overcomplicating the solution there. On the other hand, the NepsterLix version didn't seem as bad, but it's still very finnicky to do. It's remade in the L1 Pillar set in NL, meaning it has the slow rope trap just like the slow trap here in the Lix version, but they aren't as slow as you might think :P

Finally, Operation Overlord is credited to Crane/Nepster. Crane has a level called Deep Freeze, and someone can correct me if I'm wrong, but I believe Nepster's level is based on Crane's level. I don't remember having much trouble with the splat height on the right side in the NepsterLems version. This really irritated me here in NepsterLix, as I kept needing to readjust it plenty of times until they didn't splat anymore. In any case, it's just as hard here as in NepsterLems.

3 Black Hole levels left, 1 level in its own Final rank, and a full Outtakes rank of 11 levels are all that's left! :thumbsup: I will probably stream the pack one last time on Friday and quite possibly finish up NepsterLix :) The end is near! Excellent job to Nepster with the pack despite all the backroutes! :thumbsup:         

Friday, September 11, 2026 stream is over, and while I didn't manage to finish up the rest of the pack as I thought I would, I managed to solve the remaining 3 levels of the Black Hole rank, Final Frustration that in its own Final rank rather than the 21st Black Hole level like it is in NepsterLems, and finally the first 9 levels of the Outtakes rank. Here, I'm only going to attach my entire Black Hole rank and Final Frustration replays. I'll post my entire NepsterLix replay collection, including my replays for the Outtakes levels, next time when I beat the remaining 2 Outtakes levels ;) Same thing with the feedback for the Outtakes levels, I'll post that next time as well.

For the remaining 3 Black Hole levels, both A Night in Lixtown and House of the Mad Trickster were new to me, though the former is of course a repeat of Sun 20 - Dawn in Lixtown and Black Hole 7 - A Day in Lixtown. I more or less used the exact same solution as the one for Sun 20, though Black Hole 19 felt a bit harder because I think the spawn interval is a bit higher here. Nice level even if I think my solution is a bit of a backroute ;)

For Mad Trickster, probably a bit of a backroute as well. Still a nice level, even if it was one I thought would take me a while :laugh:

The Deadly Rooms of Lix - Definitely not the solution I used in NepsterLems, though my NL solution was a bit hackish from what I remember. I think my NepsterLix solution is a bit of a backroute as well, as the intended solution probably seems a bit more elegant.

Finally, Final Frustration in NepsterLems took me about 2 hours of hashing things out before I finally solved it. It's definitely the hardest X-of-everything level I ever played but it's a pretty good one IMO! :thumbsup: Here for NepsterLix, it didn't take me anywhere near as long, though it still took quite some time. I could had done the far left entrance more efficiently, and indeed I completely forgot about the blocker which I meant to free much earlier than I did in my eventual solution, but luckily it was still salvageable. Thank goodness, as it would had sucked so much to have to redo so much of the level! :crylaugh:

The only levels that remain unsolved for me are Outtakes 10 (attempted but a no solve) and Outtakes 11 (this one not attempted yet). These final two levels are repeats of a 5-of-all level but made much harder. Outtakes 9 is also one, though I was able to solve this level in my stream. So, looks like I'll finish up the rest of the pack next stream. I'm thinking Sunday, but it all depends on how long it takes me to get Outtakes 10 solved. Once I succeed, then it should just be a quick show the solution and then we move on to the final level of the pack. I had a quick look after I quit Outtakes 10 and just from the save requirement alone it already sounds really hard. I don't yet know if the skillset is the same, though it wouldn't surprise me if it's not a 5-of-everything like the original. Both Outtakes 9 and Outtakes 10 aren't 5-of-everything levels like the original in the 5-of-all rank, so it's reasonable to guess that Outtakes 11 isn't one either, as it is a repeat of a 5-of-all level.

All rightie, one last post next time when I solve all of the pack and post my entire replay collection! :thumbsup:   

You mowed through all the hard maps. Congratulations.

House of the Mad Trickster: Nepster's replay will still solve the level even if we

Change candidate

cover the rectangular hole's entire ceiling with buzzsaws. Climbers will now die in the rectangular hole. Reason to implement this change: The level will feel more honest; deadly nooks are deadly.

I'll implement this change.

-- Simon

Suggestion:
To create clarity with the timed Outtakes levels there should be the ticks according to D-Lix in the title instead of time.

"Just a quickie": 480
"It's hero time again!": 930

and my suggestion with "Time Out" would be 3180 since the level would give 210s time limit.

Thanks, it's a good suggestion to write the tick count directly into the title. That removes the guesswork for how much time passed in older Lix versions before the first spawn when Nepster made the levels. It turns out that levels started at 30 ticks, then 2 seconds passed until the first spawn at 60 ticks, and these 2 seconds counted against your time limit. (Nowadays, singleplayer levels start at 45 ticks and multiplayer at 0 ticks.)

Lix doesn't support time limits any more, but Lix shows the current number of ticks in the tweaker, and that makes ticks the best unit of time for the title. I'll earmark changing seconds/minutes to ticks in the titles (https://github.com/SimonN/lix-unstable/commit/0ba4b9cd597e35525e5d22f563c1d25ad6d03a6e?w=1) for the next release.

-- Simon

Sunday, September 13, 2026 stream is over, and I'm happy to say that after a few weeks of streaming, I have now solved all of NepsterLix! :thumbsup: My entire replay collection is attached, including for the Outtakes rank that I didn't post last time. Here, I will post my feedback for Outtakes, as I didn't do that last time either.

Outtakes Rank Feedback

A Move on the Roof - Nice level to start off the rank. Looks difficult but it's not as bad as it looks despite the situation they're in at the very start and the high release rate.

The Flight - Nice variant of a builder trick but with the batter instead! It's kind of easy to deduce the solution, given that the lack of the floater sort of leads one to discover the main trick of the level sooner or later. Also it requires players

Spoiler

to know that being flung by the batter resets the fall distance in order to help Lix survive otherwise fatal falls.

I figured out the solution fairly quickly, so after that it was a matter of executing it properly. Luckily, resources aren't tight at all, though I didn't realize until later that I was making an unnecessary sacrifice at the start. Once I stepped back a bit, then the solution was clearer to me.

The Shortcut - Not hard at all and probably a backroute, so maybe that's why the level's in the Outtakes rank?

Poor Wee Creatures - Twin Edition - This level is in NepsterLems, I think the Neutron Star rank? For some reason, the level feels a lot easier in NepsterLix, though given the solution I used, losses added up much quicker than I thought they would. Even then, I didn't feel the save requirement was too much of a problem in any way. Probably just the fact the Lix version gives platformers is what makes the level easier compared to the NepsterLems version, which sticks to classic 8 skills only.

It's hero time again! - 1min - Also in NepsterLems, where it also has a 1 minute time limit, as the level title is kind of a throwback to being a Mayhem 3 type level: 99RR and 1 minute time limit, with the only thing that doesn't make it Mayhem 3-like is the fact you're allowed to lose 1. My solution here does fulfill 15n + 30, though it seems that Lix D uses 15n + 45 instead, so either way my solution finishes on time (according to running the replay in Lix, the save requirement got met at 875 ticks [icon turned green] and exits out at 881 ticks.

We all fly down - Quite possibly the hardest level in the entire Outtakes rank outside of the final 3 levels which are much harder repeats of 5-of-all levels. I was stuck here for a while, though it seems I simply just had the mistake of when and where to assign the blocker and second digger in order to

Spoiler

make a step so that the others who are still yet to spawn don't splat, as it's really slow. Also that was a really nice touch that the digger needs to go all the way down before bashing, and that she needs to release the others that are trapped in the pit at the bottom :thumbsup:

Here, Lix autosaves my replay for the level as being the 11th level of the rank by prefixing with an 11 even though it's listed as the 6th level in the order.X file for the rank. As such, all my other replays in the order are shifted over a spot. Looks like an accidental misnumbering of the level file name there, as it's prefixed with an 11 instead of a 6.

Just a quickie - 30sec Also in NepsterLems with a 30 second time limit. I revisited this level after solving all of the Outtakes rank to get a new solution that does finish under the 15n + 30 formula, as that was what I was going by with the time limit levels. As such, the solution also finishes under the 15n + 45 formula. Think I remember doing something slightly different in the NL version though it's pretty close to my second Lix solution IIRC. Here, my second solution has the icon turn green at 451 ticks, so it does seem it should be possible even under the 15n formula (just 1 tick over).

edit: Yup, it is (3rd replay attached), where the icon turns green at 405 ticks and the last required Lix fully exits by around 416 ticks.

Time Out - 3min - This level is also in NepsterLems but there it has a 3 minute time limit just like the title says here for NepsterLix. Even though the level file itself says 210 seconds, not sure if the level title should reflect that or 3mins instead to match the NL version. However, as Simon has mentioned, it's better if the level title mentions the number of ticks, and I agree with this change for the next update.

Anyway, revisited this level as my original solution would time out. Here, the icon turns green at 2662 ticks and hence the last Lix required to be saved fully exits by around 2673 ticks. Thus, if going by the 3 minute time limit, this finishes under 2730 ticks by the 15n + 30 formula and therefore also finishes on time with the 15n + 45 formula.

Big Ice Block - The Challenge Repeat of 5-of-all 2 but reduced to a 1-of-everything skillset instead of the original 5-of-everything. Much harder as a result, though my solution uses a lot of pixel precision. I checked Nepster's replay and it is so much easier!

Spoiler

For whatever reason, I keep forgetting about runners being able to jump much farther than a walker! :forehead:

Stopping Stones - The Challenge Repeat of 5-of-all 4 but this time the skillset is reduced to a 3-of-everything from the original 5-of-everything. Wow, what an amazing but really hard level, though I once again made it much harder than it needed to be, after checking Nepster's replay! :forehead:

Spoiler

Ok, so it's still possible to stay at the bottom entirely. So, my comment that you need to go over the top as much as possible is moot, though hey, got to give me credit for a really outside the box thinking and solution here! :P

Lots of Small Tasks - The Challen. - Repeat of 5-of-all 13 with the same 5-of-everything skillset but made much harder with a much higher save requirement. Before I looked at the level for the very first time in the stream, I kind of had the feeling the skillset would be the same :laugh: Ok, great level to finish off the pack on and one in which it didn't take me as long as I thought it would, probably because I was really thinking on how to do the subsections very efficiently and was spot on for the most part. I even save more than the requirement in the end! :lem-mindblown: :laugh: :thumbsup: Very satisfying to solve I must say! :thumbsup:

FYI, this level is in NepsterLems but as a 10-of-everything level in the Moon rank.

---

I revisited two earlier levels after solving Outtakes 11, On the Edge of Death (Sun 16) and Gray Walls (Black Hole 2), in order to beat them under the time limit that's present in the NepsterLems version. The former has a 1 minute time limit, while the latter has a 2:30 time limit. Currently, Sun 16 is impossible to beat under the 1 minute time limit, as the last Lix doesn't spawn on time and still has a bit of walking distance to reach the exit before the 930 ticks is reached. The problem is simply due to not being able to adjust the spawn interval at any point during gameplay.

For the latter, my original solution would time out, but my new replay finishes on time. Here, icon turns green at 2237 ticks and the last Lix required to fully exit at around 2248 ticks, which is under 2280 ticks by the 15n + 30 formula and therefore this also finishes in time under the 15n + 45 formula.

---

All right, after a few weeks of streaming NepsterLix and 3 years after I had solved all of NepsterLems, I have now solved all of NepsterLix too! :thumbsup: Wow, despite being many times harder than NepsterLems IMO, still an amazing level pack by Nepster here with NepsterLix! :thumbsup: So, guess I haven't lost too much of my touch with Nepster's levels after all this time even though there were some solutions I couldn't remember for a time, as well as despite how some of these levels are new to me due to not being in NepsterLems.

It turns out that levels started at 30 ticks, then 2 seconds passed until the first spawn at 60 ticks, and these 2 seconds counted against your time limit. (Nowadays, singleplayer levels start at 45 ticks and multiplayer at 0 ticks.)

Lix doesn't support time limits any more, but Lix shows the current number of ticks in the tweaker, and that makes ticks the best unit of time for the title. I'll earmark changing seconds/minutes to ticks in the titles (https://github.com/SimonN/lix-unstable/commit/0ba4b9cd597e35525e5d22f563c1d25ad6d03a6e?w=1) for the next release.

Agree here with making the change to the level and also with mentioning the number of ticks in the level titles for those that were intended to have a time limit :)

Quote from: Forestidia86 on September 14, 2026, 01:58:00 PMand my suggestion with "Time Out" would be 3180 since the level would give 210s time limit.

I already mentioned it earlier, but the NepsterLems version of the level has a 3 minute time limit.

Quote from: kaywhynTime Out - 3min - This level is also in NepsterLems but there it has a 3 minute time limit just like the title says here for NepsterLix. Even though the level file itself says 210 seconds, not sure if the level title should reflect that or 3mins instead to match the NL version.

Anyway, happy to out with my feedback for pack authors and to be able to help Simon out with providing Lix feedback! :thumbsup: Thanks for the update to the rewind to previous feature for the 0.10.35 Lix release. Still need to get the approximately 30 minute video footage to you of how I use it, but that will be at some point in the future when I'm able to get to it. I currently have a lot going on and hence I can't guaranteed I'll be quick with getting Simon my video. Anyway, I of course will let him know when I have it unlisted on my channel ;)

NepsterLems version of the level has a 3 minute time limit.

Lemmings 1 runs at 17 physics updates per second, I believe NL is the same. You get more work done in 1 NL second than in 1 Lix second. Lemmings 1 takes about 3.1 seconds to first spawn. That allows you ~3,007 physics updates in NL after first spawn.

Lix runs at 15 physics updates per second, first spawn is at 60 ticks, and C++ Lix (from year 2016) counts time limits starting from 30 ticks. If we insist on 3 minutes at normal Lix speed, C++ Lix would have allowed 2,670 ticks after first spawn, which is 2,730 ticks from the artificial zero 4 seconds before spawn.

Nepster's reference solution takes 2,739 to win and even has a manual nuke at 2,808. That wouldn't have passed under the strict 2,730 tick 3-minute bar. You were faster at 2,662, you proved it's possible to put 2,730 into the title and still have it doable, but Nepster's reference replay would fail to solve. What to do?

Let's put 3,000 into the title? Round number, and it's only 3.5 seconds tighter than Lemmings 1's 3 minutes. The reference replay accomplishes it comfortably with 17 seconds to spare. And everybody else's solution passes, too.

Archeology: C++ Lix never shipped NepsterLix and people had to get NepsterLix from this thread instead. In March 2016, I put NepsterLix into D Lix. Already there, we had the mismatch of #SECONDS 210 (= 3:30) in Time Out and 3min in Time Out's title.

I conjecture: Nepster wanted 3 minutes because NepsterLems came first and had 3 minutes. Then he found 3 minutes too tight at 15 ticks/second, and bumped it to the next bigger round-looking value of 3:30. Then he (I think it was him?) put time limits into the titles, and somehow we wrote 3 minutes into the title in Lix even though that's again too tight.

I'll change the 3,180 in the commit to 3,000. (https://github.com/SimonN/lix-unstable/commit/37ca3194bbbac36487296304f797b381fa904e8e?w=1)

Correct, NL is pretty much based off of Dos, so yes, 17 frames a second.

Thanks for the info ;)

Yea, I would agree there with 3,000 as a good solution here for the Time Out level. We can always change it back or to something else later on if Nepster ever returns in the future and clarifies what the time limit should be used for the level. It's also not a big deal if it's necessary to slightly tweak Nepster's replay to have a replay proof for the level again, but yea, there isn't really any reason why we need to break anyone's replay solution here because it doesn't finish on time for the level, especially if they all finish within the same tick range.
