I really enjoyed this and made it through all 17 levels! It's definitely a slow game, though. Would be nice to be able to speed up the time - even though it would undermine the theme, it would certainly make it easier to get through when you were comfortable with the solution on a level and just messed up at the end.
Also, really nice touch picking music that seems to be roughly 60 BPM (that is, one beat per second). At first I thought you were actually syncing the game's ticks to the beat, but then it got a little bit desynced. That would be a really cool piece of polish for a post-jam build!
