Cosmosmash is a game where you control a base that must destroy rocks before they hit the ground, or you lose points. You must also prevent "spinners" from touching the ground, or your base will explode. This game is a clone of the 1981 Astrosmash video game for the Intellivision by Mattel Electronics.
SuperTux is a side-scrolling platform game. The hero in this game is Tux the Penguin, the game's only reference to Linux.

BurgerSpace is a game in which you are a chef, and must walk over hamburger ingredients (buns, meat, and lettuce) to make them fall from floor to floor, until they end up on the plates at the bottom of the screen. It requires the SDL multimedia library. It is a clone of the 1982 BurgerTime video game by Bally Midway.
