Mappy is an arcade game by Namco. You play as a police mouse and your goal is to retrieve stolen items that are scattered throughout a mansion. But be careful, the mansion is inhabited by felonious felines that will make your task a challenge. If one of these cats touches you, you will lose a life. However, you may pass through cats in the air unharmed. Use the trampolines to jump to different floors. If you jump on a trampoline four times, it will break!
