Mu-cade, described by Cho as a 'Smashup waggly shmup,' comes, like all arcade greats, with only a single line of instruction: "Keep your ship from falling down and push enemies out of the way."

Segments of the fallen snake are then added to the victor's tail for both lessened mobility and increased stability, and can be cut free for a jolt of increased firepower in a pinch.
