The game uses a fixed side-scrolling perspective. Thomas advances through five stages, defeating waves of ordinary enemies and surviving hazards before confronting a stage boss.

Players can walk, crouch, jump, punch, and kick. Enemies approach from both sides, while knives, falling objects, and other hazards require timing and positioning. A stage is cleared by reaching its end and defeating the boss; after the final battle, the game can be replayed at a higher difficulty.

Stay near the center of the screen so enemies cannot trap Thomas against an edge. Use kicks against ordinary attackers when spacing matters, and crouch or jump to avoid knives and overhead hazards.

Learn each boss's approach pattern instead of attacking continuously. Preserve lives by prioritizing incoming threats, especially enemies approaching from behind, and use the stage layout to keep opponents on one side whenever possible.
