The game of Breakit!
When I was still in high school I wrote a game. It was a cloning of the famous Arcanoid game and was written in Allegro. The unique feature of the game is that it supports multiplayer on one PC, which is something like deathmatch. Today I found the source and opened a project in Google Code. Here is it: http://code.google.com/p/breakin/ (the project is called breakin, because breakit is used for another project in sourceforge).
