Squirm

Squirm is a Snake-type game which finds you, the player, prospecting for diamonds; to your consternation, the precious stones are guarded by packs of rampaging ghosts. These supernatural spooks - for their own ghostly reasons - line up in tight, orderly ranks that march horizontally across the screen. Your task is to squirm past the ghosts and grab the solitary, blinking diamonds without getting caught.
