A space shooter game that puts the player in control of a small ship in an asteroid field. The player can turn the ship clockwise or counterclockwise, fire engines to accelerate forward, or shoot a projectile weapon. The ship broadly follows Newtonian physics - it has inertia and will keep moving in a direction after the player cuts the engines unless they rotate and accelerate in the opposite direction. Additionally, the ship’s own velocity is added to that of the shots it fires.
