In Slime, the player controls a small warship, which moves horizontally on the bottom of the screen. It is surrounded by an Absorber on either side of the bottom of the screen. Alien vessels will drop slimes from the heavens, and the player must shoot out wedge-shaped barricades, with the hope of directing slimes into the Absorbers, or at least preventing them from reaching the sea. While doing this, alien spaceships will intermittently plug your Absorbers, or shoot down your wedges. As slimes reach the ocean, the sea level will rise, and when the seas reach the top of the screen, it's game over.
Morky is a platform game, where you play as Morky and have to collect keys to open doors and jump over enemies and holes. You can also collect pills with a plus on it for extra points.
In The Crypts of Plumbous, the player has to fight alien ships who are trying to raid underground Nuclear waste storage for some unknown reason and unleash it on the planet.
