It's just regular pong. Use arrow keys to move.
This was made so it could be easily used with the Makey Makey. To connect the Makey Makey and use it plug in the biggest cord in to the computer. Then attach the smaller cords to a conductor such as graphite or water. (don't worry the electrical charge is super small and won't hurt you in the slightest.) Next attach it to the control board and attach it to what you would like to move. Finally attach one to the bottom where it says earth and hold on to that cord. Here is a sight where you could buy a Makey Makey. http://www.makeymakey.com/
