Really cool game, love the idea. I actually think the movement is good, which is something i can rarely say for game jam platformers :) The progression and upgrades are fun, maybe i wish the exhaustion upgrade price didn't scale as much cause i'm bad and it takes me a long time to get to the next one, so i gave up before i finished the game. Also the wall jumping is a bit clunky which made progressing a bit frustrating, but i cant expect much better from a game jam game :) Otherwise, really impressive game, keep up the good work.
