GNUjump is a clone of the simple yet addictive
game Xjump, adding new features like multiplayer,
unlimited FPS, smooth floor falling, themable
graphics, sounds, replays, etc. The goal in this
game is to jump to the next floor and try not to
fall down. As you go further up the Falling Tower,
the floors will fall more quickly. Try to survive
longer and get higher up than anyone else.
