Mappy (Japan) — About this game
Mappy (Japan) recovers stolen valuables from a house where doors and trampolines define the escape routes from pursuing cats. A flashing door launches a microwave wave that sweeps away nearby pursuers, while collecting matching items consecutively increases their bonus. A trampoline breaks after four uninterrupted bounces, but landing on a floor resets it. Learn a door’s opening direction before drawing a cat close, then leave the trampoline for a platform instead of repeatedly bouncing until the escape collapses.
