The game uses a side-view platform perspective. Gizmo moves through stages in the Clamp Center, jumps across platforms, avoids hazards, defeats gremlins, and collects useful objects.

Progression is stage-based. Players learn enemy movement patterns and use the available projectile attack carefully, since contact with enemies and environmental hazards can cost lives or health. The DOS release should not be assumed to share the exact level layout or controls of the NES, Game Boy, or home-computer versions.

Move cautiously and study enemy patterns before crossing narrow platforms. Avoid rushing into unfamiliar rooms, especially when a jump also requires dealing with an enemy.

Conserve projectile attacks for enemies that block progress, and prioritize safe positioning over collecting every item. Because versions differ, verify the DOS release’s hazards and controls rather than applying advice from the NES adaptation.
