Moondog

A laser cannon guards the plain of the moon. Far up in the sky the Moondog, an alien craft, wanders inside a box of its own and draws closer: first a dot, then a small craft, then a large one with a warning tone, and when it arrives it destroys the cannon. Move the cannon left and right and fire the laser, a beam that runs up the whole sky in the cannon's column. A hit scores 100 less the time the Moondog took, so the farther off it is, the more it is worth. Meanwhile four moons fall across the sky, and one that lands on the cannon destroys it too. The Moondogs come faster as you hit more of them. You have four ships; after a lost ship a new round begins with a new Moondog.

Controls: Either controller: the stick moves the cannon left and right, and either button fires. On the title, up and down choose and a button starts.
