So I decided to make a Classic version of SEB Lems for RetroLemmini. It took over a week to convert all the levels in my other level packs which were compatible solution wise with RetroLemmini. Out of 373 of my NeoLemmix levels, only 42 made the cut, the main reason being that the majority of my levels don't stick to the classic 8 skills making a conversion to RetroLemmini not possible.

36 levels came from SEB Lems itself, 4 from Lemmings presents Gotta Go Fast, 1 from Modular Lems and 1 from MegSEGAbytes.

I have reordered the levels collectively by difficulty across 4 difficulty ranks: Paradise, Bittersweet, Stormy and Murder.
Each rank has 10 levels except for Murder which has 12 levels.


Paradise Level 10 "Hurry Up and Wait" (returning level from Lemmings presents: Gotta Go Fast - originally a Marble Zone tileset level)


Bittersweet Level 6 "Until The Stars Collide" (returning SEB Lems level)


Stormy Level 1 "It's An Automatic Lock-In" (returning Modular Lems level - originally a Raymanni Toy tileset level)


Murder Level 3 "Going Deeper Underground" (returning MegSEGAbytes level - originally Medieval tileset) - one of many Flopsy/Wafflem collaborations in the pack!


Murder Level 10 "Everything Falls into Place" (a classic returning SEB Lems level)

Download the music pack for SEB Lems Classic here. It contains 22 tracks and is 93MB.
SEB Lems Classic for RetroLemmini Music pack.
For the music pack download above, place the folder marked "seb-lems" inside your resources/music folder, the pack is programmed to use the tracks inside this folder.

Download the pack at the bottom of this post, the download also includes the solve replays. Extract the download to your RetroLemmini folder.

The colours in the latest post look fine to me. Green for the title and save requirement -- green is kind of the default colour for Lemmings, and it helps the important lines stand out. Yellow for time limit is good, as that catches the eye, and you want to be warned when there is a time limit. For the buttons, maybe green for the mouseover colour?

I like the austere appearance when the optional lines are not present. It shows that we're not bogging the player down in a ton of information; here's what you need to know, now start playing.

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!

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! 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!

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! 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. 

This is the color scheme for the next version. We can test it to see what we think and fine-tune it later if necessary:

Use GREEN for everything except the following:

TEAL/CYAN = save requirement is met | 'cut X tasks' | only neutrals remain*

YELLOW = level has a time limit

RED = not enough lemmings remain | time has run out (alongside Simon's red sand timer)

BLUE = panel button hints

*Decided to keep this in because it is useful info which might not be obvious by looking at the gameplay area (e.g. if the lems are in a bunch). Shall we change the lem icon to neutral colors as well...?

There are some inconsistencies here, but we are using less colors, and when color changes happen, it's now more obvious why. So, we're closer to the goal, but more could be done.

Thanks! I've merged my post from the NepsterLix topic to this one!

Hi,

Hi,

Flopsy has started converting some of his singleplayer levels from NeoLemmix to Lix. I've got Flopsy's first batch of 26 Lix levels.

And I'd like to playtest always-insert. I.e., airclicks cut the replay, but clicking lix doesn't cut the replay; instead, other lix' futures is preserved. How will it feel?

Let's see:

As I've recently finished streaming kieran millar's QFK2, his custom L2 pack, I've decided to go back to roots a bit before taking on his custom L3 pack. In about an hour, at 5PM PST, I'm going to stream some NepsterLix. I've already solved all of NepsterLems back in 2023, though it took me nearly 3 years to do so, all courtesy of a level in the Black Hole rank which I was stuck on for a very long time. Am I still up to snuff with Nepster's levels after all this time? Let's find out!

Sorry, YouTube only, not Twitch. I don't even have an account for the latter, and I don't see myself signing up for one anytime soon

By the time I decided to give LPing a try, I had already solved too much of NepsterLems and hence decided to solve all of the pack offline. With NepsterLix, I can at least stream the entire thing from scratch, as I have never played any of it and some of these levels should be completely new to me due to not being ported over to NeoLemmix.

While this is to see how I fare with Nepster's custom Lix pack, this will also be as a way to provide feedback for the rewind to previous assignment feature, which I suggested to Simon to implement from a few years back. I'm sorry I left this hanging for so long without providing any feedback before it made its way into a stable Lix release During gameplay, I suspect I will miss the NL implementation, but you'll understand why once you see me use it a few times  

Added some extra spacing, recolored the lines, and removed the 'Release Rate' line:



The 'Release Rate' line not being there does look better if the level has a time limit. Without either (and especially if the level doesn't contain Neutrals or Zombies), the Preview screen suddenly looks a bit barren:



I prefer the button text being blue.

Thoughts?
