Other players than myself are probably better off picking levels as my taste in levels is not the most popular!

All I would request is that you consider using NeoLemmix Community Edition for your showcase, as this would be a great opportunity to present/test some of the upgraded UI features (many of which I imagine would be particularly useful for speedrunning*), and potentially expand the player base.

Best of luck with the showcase, I look forward to watching your runs!

*Some examples:

• Mouse wheel framestepping
• Panel button specific hotkeys
• Nudge viewport hotkeys

I am not a Speedrun junkie, but for point 2 and 3 of your list my initial thought is: https://www.lemmingsforums.net/index.php?topic=6062.0

Just take a look at the top 3 levels from the all the previuos "Level of the Year" contests and pick your favorites!

There you should get a better overview than just one or two people telling you some favorites! 

If you need replays for those levels, look at YouTube or ask the authors directly.

If you want levels directly tuned for difficulty I would hint at the last ranks of Lemmings Uncharted, Lemmings Destination, NepsterLems and Lemmings United.

Heya,     

I'm currently considering submitting a showcase for UKSG Blue in October 2026
UKSG is a speedruning event, held three times a year in Glasgow. They fundraise money for CRISIS to help people out of homelessness.
But not every submission must be strictly speedruns that appear on leaderboards. I often submit retro games (though mostly point and click/puzzle adventures, see Here for examples).
I consider NeoLemmix at least TAS-adjacent, as you have control over every input on every frame, even if the goal isn't necessarily to get the fastest time.

My current plan is to showcase three things:
1. Speedruns of the vanilla Lemmings Mayhem    category but with NeoLemmix solutions (where I want to showcase fast solutions as loaded replays to these, played back at fast speed and provide some commentary).
2. Crazy  levels solvable with the original 10 jobs, but requiring NeoLemmix for the inputs. So if you have (or have seen) some crazy levels with crazy solutions that only rely on the original 10 jobs, please show them off here.
3. Anything goes. NeoLemmix  + Lix    , Custom music, terrain, contraptions, solutions, skins, show off what you loved to create or loved someone else create.

Now to be absolutely clear, this is not a level creation contest.
There is for a submission, there is no guarantee that it will be accepted, so please do not put any additional effort into this.
If you have or have seen
1. A fast solution for an original Mayhem level,
2. A level showcasing interesting interactions with vanilla jobs,
3. Your favourite levels or solutions,
I'd be delighted to collect them here. Obviously I'll give proper credit to every creator should the submission be successful.

Don't worry too much about part 1, I'm aware not everyone likes optimising solutions for time, I'm happy to take care of that myself, if nothing in particular comes to mind.
I want to include this part to keep the theme of speedrunning in the submission.

Basically what I'm asking is, what are your favourite levels that you'd like to see in a showcase like this?

Alright, I will first create the topic and with all the level image links and dicide the groups as always.

It will be 5 groups with 7 levels each and 2 planned survivors per group.

QuoteI hope that Icho keeps the first poll open until at least Thursday, July 2nd.

I will run 3 polls at a time again with each round except the last running for 3 days.

I can start on monday or tuesday if you have trouble voting otherwise. I rather catch as many people as possible for the vote than starting 2 days early. 

Also then people can already view the groups.

Thanks for your comments, MASTER-88.
I'm making slow progress with the remaining levels. Probably won't bother with level 10, where sequencing 30+ Diggers would try my patience too far. Have solutions for levels 17, 18 & 20.

Levels 17, 18, 20

Level 17 "Tunnel Scenario": 4 trapdoors with 2 lemmings each. The required strategy quickly becomes apparent, but there's a problem: the mineshaft going down to rescue the bottom left group leaves too high a step, so a kink is needed to lower its bottom part. From the skills provided I thought that the 'Basher-Blocker cancel' trick may be the intended solution, but I could not get this to work so tried a 'Miner-Blocker-Miner cancel' trick instead. This did work, but then I realised the Blocker was not needed. So my solution has skills to spare.
Level 18 "Stairway To Heaven": another breather level, prior to tackling 'Decimation.' I looked at various ways of separating out 1 or 2 advance lemmings before deciding the simplest way was the best – insert and then remove a Blocker. The provision of 2 Climbers led me astray until I worked out that I was better off using just 1. But overall not too difficult.
Level 20 "Havoc Highway": a level of 2 halves. In the first half the challenge is to advance the pioneer lemming while evading the zombies, and preventing them from following the pioneer's path, without using too many skills. In the second half the challenge is to reach all 9 buttons needed to unlock the exit. I kept on running out of Miners because I was being inefficient in evading one obstacle. My solution uses every Miner but has Builders and Shimmiers – and plenty of time - to spare.

I've had an enjoyable time so far with this pack, which stretches my puzzle-solving skills to their limit and beyond. So thanks for that, MASTER-88.

Attached zip file now contains my solutions for the 14 levels in the final rank that I've completed.

All rightie, sounds good. I appreciate you wanting to give my fix and updated Oh Yes! another go to see if it really does hold up to be the hard level it's supposed to be now

You'll also notice that all levels of mine you've played except one don't have time limits. I think you perfectly understand why "Quick Lab Rush" needs it after having solved it the intended way and trying what I thought people would try and falling for its trap

Spoiler

Otherwise, you would be able to take the long green walkway out to the left at the top with the sliders and hence you won't need to catch them with the platformer at the bottom

It's just like I promised you from a few years ago after you played my "Stop Blowing Up My Construction Work!" and complained of me possibly slapping one on just for the heck of it: I didn't arbitrarily do so, and it originally didn't have a time limit (and the first few updates didn't either), and after having considered all my other options (pickups, steel, etc), I decided the best way to fix the backroutes by you, geoo, and Armani was to put in a time limit while also making sure the solution doesn't become too obvious from using other fixes instead. Plus, I have plenty of levels that don't have a time limit anyway

Along with that, it is true that I could had used

Spoiler

OWAs for my kaywhyn's Organic National Park level instead of the visual clutter and not the so clear blue vein steel I resorted to, but again, IMO it would had made the solution too obvious.

It's also true that I'm not happy about how the intended solution has become way more precise than it needs to be, but well, sometimes that's the way it goes with level designing and with how the level kept getting backrouted

• 3. When you hover over a lix without future assignments, still say "Click to insert."
• 4. When you hover over a lix with 7 future assignments, say "Click to replace 7 future assignments."
• 5. You still need the tweaker to cut a single lix's future without assigning anything to her. This is a problem, but the scissors panel button wasn't the answer to it in 2023.
• 6. Opening/closing the tweaker doesn't toggle the mode, unlike Lix 0.10.32, because there will be only a single mode.

This is now implemented. After playtesting, I'd like to put it into one of the next releases. (Current is Lix 0.10.33.) I'll eventually livestream a round of playing with this in July, 0-20 days after I've finished streming Level of the Year 2025.

Many little things to tell WillLem, tan x, ... later. The main recommendation is: When air clicks cancel the replay, don't mistake an unassignable lix for air. E.g., when you filter for direction and hover over a wrong-walking lix, don't consider this air. E.g., when you have basher selected in the panel and hover over a basher, don't consider this air. Clicking here should neither assign nor cut the global future.

Thanks for the backroute fixes for Molten Problem, the timing is good. I'll play again on Wed Jul 1, 17:00 UTC. If we fail to solve it, I'll watch your full coverage.

I think this is the first year where I really play everything. Gone are the days where I play NL for 1 hour and then quit for months in frustration.

Levels are tough, but that's good. Games must be hard. It would be no fun playing only easy games.

I hope that Icho keeps the first poll open until at least Thursday, July 2nd.

But we don't care, do we? We'll stream all the nominated levels! It doesn't matter if Icho conducts the first poll next week, we'll go through all the entries for 2025.

The next stream will be on Wednesday, July 1, starting 17:00 UTC = 19:00 CEST.
https://www.twitch.tv/simonnaar

We have 6 unsolved levels to play:
Dexter's Prologue
Dexter's Ring of Fire
Dexter's Subjugation
Dexter's Unstable Egress
kaywhyn's Oh Yes! A Hardcore Molten Problem (re-solve, kaywhyn fixed our backroute)
kaywhyn's Oh No! Another Hardcore Molten Problem

These streams have helped me back into NL and Lix. I'm happy how I've stuck to it these weeks.

Now I have recorded and post the rest of the LOTY2025 videos!

Part 4: https://youtu.be/iuvPgFK4y4c (Guigui's levels)

Part 5: https://youtu.be/sIih30r-gWw (my levels)

Part 6: https://youtu.be/taOhAUz6DXU (everyone else's levels, the final Mixed rank)

I've also reattached my entire replay collection, with a new replay added for GigaLem 2 so that the zip has two replays for it

I'm also reattaching my updated Oh Yes! and Oh No! levels since I fixed JawaJuice's and Simon's backroutes for them in the last few days They're also in reply #15 several posts above.
