Let's do a demonstration:
Pick up any level from original Lemmings, play it with DOS Lemmings then try it with any version of NL 10.xx again with any version of NL12.xx and finally with any version of NL CE.

Now try this attached SLX with all if the above... You can not. İt involved two skilles not supported by NL. Balloons and spearer.

I am currently using SLX and happy with it. Especially because it has classical mode as well. I can play both NL and SLX levels in the time
We are all lemmings fan let's enjoy the game and have fun  let's GO.

A typo error in the PDF file, SLX has the most points not NL

Hmmm, just an idea: we already support spectators in multiplayer, and watching a replay is similar. We don't need to have identical UI for playing vs. spectating, and when watching a replay we could have a dedicated button to start playing. Some buttons, e.g. Nuke, are not relevant for watching a game. Skills are relevant in the sense that they need to readable, but they can probably be smaller since they don't need to be clicked (and arguably maybe some spectator controls to view different players' skill counts could be useful).

I'm not entirely sure that skill variety (a category that's very easy to inflate with crap - not that engines tend to do so, but still) is worthy of awarding 200+ points, when things like the amount of content available only award 10 each.

The next version of RetroLemmini has a batch replay checker (similar to NeoLemmix's mass replay check). I've added a menu item for it, and was thinking the icon could be a red builder rucksack.

I've attached a prototype that would be usable, but this would definitely benefit from your rendering skills.

If you'd like to have a go at this, or if you have any other icon ideas for a batch replay checker, your input will be most welcome.

Is Superlemmini/Retolemmini a miner and a basher can cancel each other out whether in the same direction or the opposite direction.

Example:

In the same direction: Pimolems Hurricane 03 (The Warehouse)

In the Opposite direction: Gronklings level (The Isle of Skye)

I can sympathise. I wish I'd discovered programming in my 20s rather than late 30s, but those years were spent trying to make it as a musician. No regrets of course, as it was a fantastic experience and I was very lucky to have the opportunity to develop my musical skills at a young age - it's probably made learning programming a bit easier in some ways.

In all honesty: mouse, keyboard and a monitor is the best way to play lemmings. I've tried other ways (including on a mobile device) and none of them provide anywhere near as good a player experience. Knowing this, it's difficult to find the motivation to develop a mobile-based version.

With that said, if you did want to take a look at it with me at some point, I'd be open to exploring the possibilities. The RetroLemmini source code is here.

I'm sorry I have no real idea on the scoring and unlockables aspect of the whole game yet as I think it may be hard to give before playing a good chunck of the game and seeing how hard levels are.

I tried the 5 levels demo and, coming from Original Lemmings and NL, I find the lack of time manipulation tools awkward. I'd at least give the ability to assign a skill while the game is paused. It is kind of awakard to have to unpause the game to assing skills, then pause immediatly after to start thinking again.
Also certainly give a keyboard shortcut for the pause bc going to the pause button may loose wome precious time and make you miss the skill assignment deadline if you miss the button !

Finally in the level 5 of the demo with the builder-like I noticed a bug where some Fizzles will turn when walk on the extremity of a "bridge" set under them. I call it a bug bc some Fizzles turn at this spot when others dont.

Oh and I must also say this is a nice touch to have the builders "instant" in the sense that a fizzle coming right after a builder will be able to get on the bridge. This does differentiate Fizzles from Lemmings and will avoid many headaches to players.
One must also acknowledge that the very long time builders take in Lemmings is also the source of many good levels and tricks, but here this will make the game overall easier and I think this is what you're after.

Attached is a comparison study on the 4 active softwares currently maintained on the forum. I do believe that we should concentrate on Lix and Superlimmini. NL and and SLX are almost perfect.

I'm pretty sure you're right and a basher and miner can mutually cancel in DOS (facing the same or opposite ways); I remember seeing this come up in challenge discussions, but I don't remember which specific levels.

Quote from: kaywhyn on June 28, 2026, 10:42:30 AMAs a matter of fact, the only situation I know of where both skills can stop are two miners cancelling out each other.

Interesting, I'm pretty sure I've seen a miner and a basher cancel each other in some engine, maybe DOS/Lemmix? But I think they both have to face the same way, maybe it doesn't work if they face opposite directions.
