Mappy

It's a video game released by Namco in 1983; you see, they make other games besides Pac-Man, Tekken, Time Crisis, and Soul Calibur. It was released by Midway (yes, the same Midway who would go on to do the Mortal Kombat series) in 1983. Basically, you are "Mappy", a police mouse who clears levels by recovering all of the stolen loot, while jumping on trampolines (see, each stage is a "house" with mulitple "floors"), and avoiding "Nyamco" (get it?; anyway, he's called "Goro" in the U.S. version) and his "Mewkies" ("Meowkies"). Unfortunately for you, the only "action" you can do in this game is open and close doors, but wait there's more! Some of these doors release shockwaves that send the enemies far, far away, but they eventually they come back, SO BEWARE!!! Later there was a sequel called "Hopping Mappy" but it never came to the U.S.. On the other hand, the U.S. did get an NES sequel called "Mappy-Land". Oh yeah, you gotta love the music. It's very "ragtime-y".
