Preparing a pot of green tea, and I'm feeling like writing again.
For the vast amount of Lix skills, I never looked at L1 or its source when programming their behaviors. I felt how they should/might work from playing Lemmings exhaustively as a kid, and from 2003 on in Dosbox. Differences will happen, and I'm happy about them. Most of them are about how a skill gets cancelled, the criterion was to be as flexible as possible here. Skills should be versatile.
It's better for a basher to continue in case of doubt, unless it can be proven there is an easily walkable area ahead. Basher, miner, digger terrain removal masks all depend on the sprite, which were drawn with only the target frame count and approximate stroke size in mind. Lixes falling at 6 hi-res pixels per update don't look very realistic, so they accelerate until they fall at 8, I think. Jumping climbers stick to walls and start climbing them, similar to the L2 rock climber. Jumping runners jump further than jumping walkers; this is also for versatility, consistency with L2 is basically just a bonus.
Throughout the game, I use "lix" as the plural of "lix" for consistency... People are of course free to use whatever plural they want, "lix", "lixes", "lixen", all fine. "lemmings" is also cool since it's clear what is meant, and we aren't doing marketing here.
Simon with ADmiral in Mumble right now:
ADmiral: What does "All steel removal glitches" mean?
Simon: The steel is horrible in L1. You can cancel it with blockers, and move their trigger areas in L1. It's horrible. It (L1) is the cheapest hack job.
