Hi, Syndetic. I played and completed it in about 15 minutes.
I found the repulsion confusing at first because the shape made me think it was a jump pad. I tried opening the first door by launching everyone against it and only by accidentally placing a red beacon realized what was happening.
Green and black were easy to get after that. In the level where the button rotates the platform I didn't even look ahead to see that there was a button (I just assumed my goal was on top). So that was confusing for a second. I don't understand why electricity has a countdown before killing your dudes and the chain reaction was frustrating. The blue jump pad seemed a little inconsistent on when it was going to launch someone. I feel like I got lucky with the ball in the last level.
Being able to remove objects was great! The limited use is one thing I always hated about Lemmings. I wish I could scroll by right click dragging though.
I like the melody/composition of the music, but the instruments feel cheap. The sound effects fit perfectly.
I like the idea. I'd like to see different physical properties attached to the dudes like some are really heavy and some are buoyant, etc. I think it will be interesting if you can keep puzzles more tightly focused in a small space, rather than spreading them over a scrolling area.
Since you said you'd return the favor, here's what I'm working on:
