4Music is good and the AI is competent. Too bad the gameplay is as basic as a Pong clone can be and made less fun by bad collision detection. Graphics could use some work.

6v1.1: A very simple pong clone with extremely basic gfx and bad collision detection. Sfx and music are quite nice even though they're a bit on the noisy side. Plays reasonably well and even has AI with adjustable strength. Negative points for using the Allegro 8x8 font in the menus and the game.
