Detritus is a fast-paced shoot-em-up strongly based on the old classic Asteroids. Replenish your shield with power-ups and gain new weapons. "Cleaners" appear periodically, so watch out! The keyboard controls should be self-explanatory. Written in c++ with SDL, OpenGL, and OpenAL libraries.
Yet another tetris "clone". Written in c with GLUT, OpenGL, and OpenAL libraries. Compiled with MingW/gcc on windows, gcc on os x. Haven't had a chance to compile it for linux or *bsd, but the source code's free, so ... feel free.
