Well, It IS Pong....
Hm... A few gripes I have.
The control is a bit awkward - up and down don't seem up and down, and you have to use both hands. Try using a more WASD approach (and IJKL).
The AI is wayyyyy too easy - I usually get caught up in these matches, trying to trick it, but I beat it far too easily.
You have captured the classic 'Pong' Feel, though.
