Interesting concept, even though it wasn't 3-D.
I mean, come on, you can clearly see that it's a 2-D trick. The ball simply increases and decreases size as it gets closer, and it appears to fall in a correct line of perspective when it goes back and forth from certain angles, but it's not really 3-D, so this is essentially false advertising. I don't care, though, because this is a mildly entertaining game. The only problem I see is that there should actually be a score board, so you can set it for a goal of 10 or 20, instead of just one. Also, the ball doesn't seem to get near enough to the paddle before it actually "goes off screen".
