In this game, Patrick is flying through the Chum Caverns. The player controls Patrick by holding the space bar to move up and releasing it to move down. The player must prevent Patrick from bumping into stalactites, stalagmites, rocks in midair, and cave dwellers. If he bumps into any of these, he falls and the game ends. The player earns points as Patrick flies through the caverns. Earning points gets faster after every level, but so does Patrick's speed, making it harder to avoid obstacles.
