You are Mappy, intrepid mouse cop on the trail of a gang of cat burglars. Naturally you, as a mouse, are no match for the cats so you must stay out of their way, Pac-Man style.
The only way you can get up to the higher levels of the mansion is by bouncing off trampolines - but these have limited uses. Too much bouncing and they break, propelling you down to your doom. Doors situated at key points in each level allow you to stun cats (oddly referred to as the Mewkies) and get by.
Challenging and inventive, this is surprisingly addictive, but probably for retro enthusiasts only.

After licensing Space Invaders, Galaxian and Pac-Man, it seemed that Midway couldn't make a mistake in the early 1980s. Then they did.
I rented this game as a kid on NES and hated it.. So many wasted weekends on poor games.. Box art was deceitful
I personally like this game a lot. It requires strategy by planing ahead though, something a lot of arcade gamers in the west couldn't handle. I still play it on my NES as well as the arcade perfect port in Namco Museum 2.

Namco's game of cat-and-mouse didn't grab attention like Pac-Man, but Den of Geek argues that Mappy's still a platform classic.
