Well, everything seemed to work, until I got a glitch...
I was playing on easy (like the noob I am :P) and doing fairly well until the computer, well, practically caught the ball. The bar went into the ball, hit it, but then the ball just started bouncing from behind the bar to in front of it, like it wasn't going anywhere basically. It was just like MismiMan's problem. So that should definitely be fixed. Other than that, the controls were decent, the game worked fairly well, and the background music was catchy. But since it was glitchy and unoriginal, I am, unfortunately, rating this 2 stars. With a bit of work, though, it could do much better.
