I realy like that type of puzzle game but could not realy play long because I feel a little dizzy and sick from that rotating background :( maybe that was a little to much ^^ but hey at least I got to the point where you can Jump with the rocket pickup.
So for a after jam version it would maybe good to have the abillity to deactivate the rotating background. Else it would be cool if you could rotate the Camera so that you can get a better view on the ball.
