It's an interesting concept but the game is very tricky to hit the stars at the right. I'm not sure if it was the number of buttons to hit on or the difficulty of getting a rhythm going. At four buttons the game could be played on one hand, making it an easier analog between the controls and what was on the screen. The other thing is that as you hit something the constellation speeds up, making it difficult to time the next hit. It may makes sense not to speed up but mark the constellation points for a set amount of time or rotations as activated and keep it at a constant speed.
