nice game! 

rate for rate? )

Nice idea, love how the cat is jamming to the music while moving.

The jump and general movement felt a little bit "draggy" though (you could try canceling the player's y-velocity when jumping, makes it feel more reliable and maybe make it a little higher and the movement a little faster).

I also liked the idea of connecting stars and the different coloured energy levels. I think I might have preffered being able to drag the camera around instead of using the Q -> WASD controls and maybe have the camera zoomed out a little more when connecting stars.
