Counterclockwise, or as I like to call it, "3-D-battle-Snake-like-nausea-inducing-shooter", is essentially just that. You control your ship with the arrow keys like a 3-D version of the old Atari "Snake" game. You fly around the constantly changing battlefield, dodge blocks and tails, and try to shoot down the other snakes. Apparently a remake of the 1983 Spectrum game "Knot in 3D". Made by the creator of "Rescue: the Beagles".
