The action uses a single-screen vertical playfield viewed from above. The player moves the shooter around the lower portion of the screen and fires at the centipede and other creatures.

Destroying a centipede segment can split or redirect the remaining body, while mushrooms alter enemy movement and create obstacles. Fleas add mushrooms, scorpions change mushroom behavior, and spiders threaten the player's lower area.

The objective is to survive successive waves and earn as many points as possible. There is no conventional inventory, branching story, or role-playing progression; difficulty comes from enemy density, speed, and increasingly demanding attack patterns.

Keep moving instead of remaining in one position, especially when spiders enter the lower part of the screen. Clear mushrooms when they obstruct firing lanes, but avoid letting the playfield become crowded.

Aim for the centipede's head and watch how shooting body segments changes its route. Prioritize threats that are closest to the shooter, then return fire to the main wave. Use the edges carefully: they can provide temporary space, but they also limit escape routes.
