It needs more polish. The acceleration and deceleration are really annoying and hard to control. the jump height and distance are weird should they be longer with your speed or should they be the same length as it is now? I think the boxes should be in more dynamic places to shoot at and correlate to the movement you're doing along with the level. The UI is effective but needs more work on the visual. It's fun to play when you get high speed and can do some more dynamic moves so if you focus on improving both this game will be awesome.
