They're darn good editors though. Just to think we can make Lemmings romhacks on consoles now. No longer locked and bound by PC and mouse.   

I'm talking about the website buttons, not the editors, Genesis and SNES are using the the wrong title screens in the editor selection menu, the button that has the Genesis logo is using the SNES title screen, and the the button for the SNES editor is using the Genesis title screen, the graphics should be swapped

I have cleared this first batch of levels you gave to us Vexar.

Those were very pleasant levels to me, clever and classical puzzles as everyone love them. Some were quite straightforward solves, while others required more thoughts from me. None seem unfair to the player, the main matter is to use skills to their full extent.

Now you said you feared backroutes, so please be aware that you may find many of them in my solves. I often end with left over skills (btw, I love the oldstyle way you give bombers everywhere when you're not allowed to loose lems) or save more than required. This does not mean that the level is bad to me, just that our brain are not wired the same and that I may know some NeoLemmix weird techniques that were impossible or not easy to perform under WinLems (which I never played).

Here's a quick breakdown of my solutions :

Spoiler

Remake 1 : nice starter, beware where/how to set the turn for the climber.
Two exits but I used only one, which seem to be a recurring fact in those levels. Maybe are there some repeat levels not available here that make use of both exits ?


Remake 2 : straightforward solve. Good use of diggers and stairs so as not to splat.

Remake 3 : I love this one ! Nice bubble environment and a beautiful walk for those lems all around this level. It took me some time to figure out where to put that final builder rescuing the whole crowd.


Remake 4 : The solution appears fast enough considering all those builders you have. There seem to be extra destructive skills and save requirement is quite lenient, so I started to try to optimize to save many more lems ... until the evil timer came into action ! It turns out that the whole point is to try to save time, is this what the extra destructive are for ?
In the end a good level with a 2 step solves : see the solution, optimize time it takes to execute.


Remake 5 : First real deception of the pack to me : the climber is not where it seems. I also love how you give only miners here whereas bashers would make the level way easier, miners force you to leave the comfort zone and use the whole layout 
Very nice level and I think I have intended solution seeing how I have no leftover skill and save the exact requirement.



Remake 6 : Pretty hard to gain all this height with so few builders and a single miner. I resorted to a zigzag blocked miner.
Though I think I have a backroutish solve here because I save an extra lemming (certainly a blocker) by containing the crowd with a builder on the left side at the beginning.

Original 1 : First level I played in the batch, and it stuck me for way too long !
In the end it is somehow a compression level and both exits are used, very good one

Original 2 : This one was straightforward, builderfest as some may call it. I dont mind it from time to time.

Original 3 : This level left a weird feeling to me. In the end I save the exact number of required lemmings and use all skill, but I cannot help but think this is not what you expected. Is that part with miner + digger to reach the diagonal shaft correctly done ?

Original 4 : Boths exits used and the two crowds helping each other make this level a very nice one !
It took me way too much time to figure out that you have the contain the bottom crowd with a builder, to save a blocker for the ending part...

Original 5 : Just Cross The Wall had me stumped for 2 days as mentionned earlier. This is why I resorted to obscure techniques of height gaining through walls.
I think you'll call that a bad backroute seeing that I have a digger and the climber left, and do not use the whole level, at all.
Well, blame it on the level's title : I just crossed the wall !

Original 6 : three independant levels in one, be warned that some players may not like those kinds of levels here. Of course I solved each level independantly at first, using as few and disjoint skills as possible for each, then solved them all simultaneously as the title implies.
I have many leftover skills, and think this level has a very high number of different solutions !

Original 7 : Definitely my favorite level here 
This has to do with how I was not able to solve the Crazy rank Dolly Dimple level in Oh No More Lemmings as a kid. And this level is just Dolly Dimple on steroids, I love it !
It is also quite deceiptive in the place where you have to store the crowd, and how to handle the ending part with those miners.

Original 8 : good looking brick level. Seeing the layout, one quickly removes the rightmost exit from the equation, though you are left with tons of possibilities with just the left one still.
I used a lem from the upper hatch to create a path for the bottom one, he was ahead of the other just enough to build over the gap, nice. The solution also uses an air-builder lem for some frames !
Though the whole solution sound hackish because of leftover skills and the dense builders concentration I made to ensure no lem gets trapped in the left pit.

Original 9 : Compression Method, at least the title is clear.
Save requirement is 8, but you teased me with silver and gold talismans requiring to save respectively 9 and 10 w/o blocking, and with a title that sounded like a challenge to my compression skills ?!

So I went havoc and used "assign climbers one after the other to slow lemmings down, and use an awful lot of fast forward" to compress a bunch of lemmings almost pixel perfect ; the time is takes to achieve this is over 30 minutes on the ingame timer. In the end I save 14, platinum talisman ?

Sure, I could get across the wall and am currently trying to solve Original 8.
I'll definitely write a little heads up of my replays when I'm done with Original, and maybe Remake too if it is not too long nor hard.

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! 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! 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!

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 See my video stream for the explanation, especially if you're not too bothered by spoilers 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 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!    

Oh that's so adorable! I want one!

The website uses the wrong title screens for the SNES and genesis version, the SNES title screen has the Genesis Logo, and the Genesis title screen has the snes logo, they should be swapped.

Stream is over and was on Wednesday, September 2, 2026:

It'd be amazing if the pack makes it, I'll make haste to improve and even add levels before the video is uploaded Flopsy, or I'll splat trying

Quote from: Guigui on September 01, 2026, 09:20:27 PMNice level design with some deceptions here and there.

Also Guigui, I'd love to hear suggestions, after all this is a very "old" pack (started in 2010) and I want better levels, so everything is welcome! Feedback will help me a ton

Some replays would be nice too, backroutes kept me from sharing this pack, but I'm really interested in the gameplay even if you didn't solve it, maybe the level is misleading somewhere and is actually poor design from my end

Thanks for the comments
