Love the theme of the game! The movement are a bit slippery, although that may be intentional. One thing I noticed is that very time I killed the "cosmic hedgehog?", there was an on-death particle that dealt damage to me. Not sure if that was intentional as well, but that mechanic really threw me off. However, I really liked the jump timing mechanic and the ability to shoot! Every time I encountered a pit, I got pretty nervous with my jumps which made the game fun.
