The game-feel here is really, really impressive! A nice crunch to everything you do. Although, I did have to mute the audio because it got a little grating.
I love how well you used the games simple rules to create some really cool levels early on. However I found that the later levels were a little too reliant on how kind the physics were feeling and less about figuring anything out. That's common with jam games though.
Really, really nice work, again can't overstate how *good* this game feels.
