Take a look at my Projects page to play my Pong clone. This is the first game I created in Unity so it’s pretty basic and I only used JavaScript. I used GIMP for the background and Audacity for the sounds of the ball. The game features Single Player and MultiPlayer modes. The Single player will put you up against the AI while in MultiPlayer the left paddle is controlled with WASD and the right paddle is controlled with the arrow keys.

Head on over and try it out!
