imo, music and graphics are on top. The game feels well rounded except for some polishing. But that is more than fine for a 3-days game jam :D
If you wanna continue work on the game after the game jam I would have the following feedback: The colliders of the stars were a bit small and because I could only hear that I selected a star but not see which one I selected I was sometimes unsure which stars are going to form a triangle now.
