use arrow keys to move, and a and d to rotate your character. Try to beat the super good AI. There is a very easy way to beat him, however. Will fix that soon. You are a sneaky cheater, so you can cross to your opponent's side. Also, you are so good at tennis that you can hit very weirdly. There are 5 sets, if you win 3 sets of 21, then you beat the ai.
