First off, I like how floaty the jump is, but I feel like the controls would be a lot tighter if there was more air resistance when jumping. Also, having to go around each stage 3 whole times feels tedious, especially when nothing changes each lap.
I think that the player should either just have to go through the level one or two times, or there should be something that changes each lap, like the obstacle positions. Finally, each level feels very samey, which I think could be helped by focusing on having more unique mechanics in each level, like moving platforms, enemies, etc.
