MAPPY
猫鼠追逐
Mappy is an action-puzzle game developed by Namco in 1984 for the Nintendo Entertainment System. Players control Mappy, a police cat pursuing a gang of mice thieves through multi-level buildings. The core gameplay revolves around chasing mice through rooms and corridors while strategically opening and closing doors to block escape routes. The trampoline mechanics allow Mappy to reach higher areas, adding vertical exploration to the horizontal maze-like layouts. Each level features increasingly complex room arrangements that require careful planning to corner and catch all the mice before time runs out. The game supports two-player gameplay, where players alternate turns attempting to achieve higher scores. Controls are straightforward: directional movement and a button to open doors. Mappy demands quick reflexes and puzzle-solving skills as players learn optimal routes and strategies for each stage.
