Potentially good,
Look, I've got a few quick criticisms with your game:
1) You don't get "game over" when you run out of lives - you simply go into negatives. Insert a line in your reset saying "if lives < 1 , end" etc.
2) Level 3 is impossible :s Spent a good 10 mins trying, but the ball acts like a square and so does not fit between the diagonal boxes mate.
It's a good simple game concept, but until you get the interface to work, it'll be frustrating to play. Fix the bugs, re-upload, and you'll do just fine :)
