This is a clone of the classic game Gravity Wars, in which a couple of starships fight while being attracted by the gravity of a star centered on the screen. This is a 2-player game. The graphics of the game are quite simple, but they are completely rendered real time by drawing polygons on a double buffered screen. Each player moves using different keys (cursor keys + keypad zero for first player, wasd + space for player two) and has to destroy the ship without being hit or falling into the central star. The player must also take into account its fuel tank, otherwise his engines will stop.
The game is completely configurable (star mass, ship mass, rocket power, etc.) by pressing the P button.
