I can really tell how much work your team put into the jam! I liked the character, music and concept for the game. If you do a future build I just have two suggestions and both of them are gameplay related. Sometimes there were blind jumps, and I think in a platformer that is really hard because from the player perspective it seems like there is nothing they could have done but guessed and failed, so keeping at least the next jump in view would help with that. My second idea is checkpoints, with platformers this hard I think checkpoints encourage the player to keep trying and get better. Fun game though, I really liked that ending a phase in the middle of a platform gave a super jump!
