Game of Harmony

Are you smart? Do you have quick reflexes? You are a single spinning sphere. You face a series of fantastic computer-generated puzzles - 50 of them. Your goal? Knock similar balls together and make them disappear. Sound simple? It's not. Each puzzle is different and requires a different strategy. Hit the wrong balls together and they multiply. If you don't clear the screen in time, the whole thing explodes. Whatever you've done before, forget it. Harmony's a whole new ball game. Beat this baby and you can call yourself good. Until then, you're just a pretender.
