I enjoyed it! if you can I'd make it so that you can move  diagonally as that kept confusing me - but I loved the bouncing and screen shake andhaving to ctach your orb.

I really liked the projectile mechanic, however the spawning of the ghosts, should be more random, in my opinion, to discourage the player standing in the middle of the screen, catching and throwing the projectile. Otherwise, well done!
