Good concept and some cool puzzle ideas and possibilities! Some big Portal vibes which I really enjoy. The issue already mentioned with characters stuck in previous actions made it difficult to progress, though.

Can definitely be interesting when worked on for a bit longer!

I liked the gameplay system and the versatility of how it manages the time-clones mechanic, from opening doors for yourself to giving platforms for yourself to yeeting crates across the level to yourself. The ability to reset just the current lemming instead of the entire puzzle is a good design that feels sorely needed in some of the other time-clones games in this jam. The presentation is quite good as well.

I did notice a bunch of jank, which ranged from charming to game-breaking.

• In level 2, I found some cheese where the third lemming can just barely make the jump over the first gap without the crate. I kept trying to make the second jump and failing, and I was going to complain at you for not playtesting until I realized that jumping directly was not the intended solution.
• In level 3, sometimes the first lemming's actions would not play back correctly on the second loop - it would not grab a crate that it had grabbed before. After a couple tries I got a run where it worked properly though.
• In level 4, in addition to not figuring out what I was supposed to do, I encountered a bug where when I switched to the second lemming, I would lose control of my body as a recording from a prior timeline played out. I stopped playing there.

Kept running into a bug where I wouldn't be able to control one of the lemmings. It would instead playback a previous loop, even after hitting x to restart.

What I could play, the puzzles were enjoyable to work out.
