Ok, first problem: don't submit your game as many separated files, put everything in one zip, pls xD.
The game isn't very interesting, nor fun. You just have to make a few jumps with that ball. And apparently the game is incomplete, as after the second speed boost, (the one which you have to jump) you can't proceed.
The visuals are not good either, as they are basically only one spheres and cubes.
The best thing about this game is the music. Amazing job by your band.
