Basic Pong clone with an in-game shop where you can buy other ball colours for in-game money.
As previously stated, control hints would help new players. It would also be nice to move the paddle with the mouse.
The pad's speed is pretty slow and the ball should be able tobounce off in different angles, depending on where it lands on the paddle. otherwise it gets pretty boring really fast, as it just feels like watching the "DVD"-Logo - just with a paddle...
