Man in space is a game where you play as a man trapped in space, similar to asteroids.
The game-play is based around a simple principle where if you were in space and fired a gun it would propel you in the opposite direction. The player must destroy the incoming asteroids in order to stay alive while simultaneously using the gun to maintain control of the spacemans velocity and direction. Game-play should be very simple as the challenge of the game will simply be to see how high of a score you can obtain.
The game should feel like a constant struggle to maintain control, in an isolated world which becomes more and more chaotic.
