I was playing with some 3D rendering stuff and ended up making a tennis game.
Play against AI or with up to 4 players.
Z to hit the ball. To hit the ball in different directions you need to hit it when it's off to your side. So the further to your right the ball is when you hit it the more it will go left.
X to do a power shot. Whenever you return the ball during a rally you will build up power. You can do a power shot anytime you have power in your meter, but the more it builds up the faster your shot will be.
