Make it more interesting!
It's a solid game, except that the angle the ball takes off the side wall is completely unnatural... however that's the only real way to score a point - after playing for about 10 minutes with the score at 1-1 I just got bored of it. You either need to make the computer's AI a little less perfect or make your paddle less controllable - with the mouse, you can position the bat wherever you want in a split-second. I liked the perspective view of the court though, looked very nice. Decent but ultimately boring. 2-players would be nice!
