The game is a side-scroller in which you move along a looped course, trying to stay ahead of a giant snake's head as it swallows the level (its own body) behind you. The goal is to escape by cutting through the snake's body, which has randomly generated depths at different points, and then dropping through the hole you've made. There is a delay on the attack you use to cut through the body, so you must start digging holes and then run away to stay ahead of the snake, and keep working at the same holes when you come back around the loop.
