pretty good, as far as a pong game goes... i think the option to use the arrow keys would be pretty good, since i lost a few points when my mouse went off the game screen.
but that thing where your avatar comes up is interesting. imagine if you did that to other games... you're at the end of a game, a giant boss comes up, and it's face... IS YOUR AVATAR! awesome...
