Nice, just the right amount of addicting and annoying XD. If you don't mind a suggestion, it might be easier to control the ball if the gravity or the jumping took longer the more you held the button down that way it might be easier to tell how far and how long the ball will be in the air. To a point of course you wouldn't want the player to fly around or anything.
Also it was slightly shallow, I do NOT mean that as an insult it's just that one button interaction isn't exactly deep.
