This game is really great! It feels awesome to play an the art style is purely amazing! I really hope you'll continue to work on this game after the jam is done!
Also, maybe adding some checkpoints to it so you don't have to replay from the beginning of the level. I got a bit annoyed at the level where you have to dash trough 3 enemies over spikes. (but the art style made it impossible for me to stay angry =D)
