USER INSTRUCTIONS: Use the arrow keys to move the white spaceship, space to fire. WASD steer the black
    spaceship (if available), it can fire with the X key. The goal is to keep your hitpoints (displayed
    in the small striped bar in your color) above 0. (TODO: scoring)
    The objects spaceships sometimes drop have the following purpose:
        Clock: makes your gun(s) shoot faster
        Arrow: makes your guns shoot parallel missiles
        Skull: takes some of your hitpoints and enjoys munching them between its teeth
        Red Cross: gives you a small amount of hitpoints
        Angle: spreads your missiles a bit
        Two Laser Beams ("+1"): Adds one gun to your ship
        Rainbow Laser Beam ("++"): Improves your laser beam (but resets the number of your guns to 1 and
                                   resets its speed to the starting value in exchange)
