Cavern Creatures

Cavern Creatures is a vertically scrolling shooter for the Apple II written by Paul Lowrance and published by Datamost in 1983.

[2] The player controls a small craft, navigating it through a series of winding caverns and tunnels while shooting or avoiding obstacles.

The caverns scroll from the bottom of the screen to the top at a fixed speed, so the player must always move forward.

The obstacles filling the tunnels are mostly the eponymous "creatures" and appear as simple icons like smiley faces, floppy diskettes, birds, eyes, apples, bunches of grapes, Pac-Man ghosts, baseball hats, turrets, etc.

The craft is destroyed if it strikes any object or the cavern wall; a new one can be put back into play at any position on the screen.
