i liked this a lot! reminds me of a laid back version of Spacechem. there were a few bugs but thankfully they weren't that much of an issue due to the level select. i thought it was a really great use of the theme as well, and the final puzzle forced me to be clever and use all the mechanics. would love to see some tougher puzzles!
i really like puzzle games like this where there isn't one fixed solution per puzzle. the UI and the art felt satisfying. may have just been a personal problem but the low contrast of the treadmill icon caused me to think that option wasn't available on the first puzzle, and i tried to solve it using only claws (which isn't possible).
