Rompers

Rompers (ロンパーズ, lit.: Ronpāzu), is an arcade game that was released by Namco in 1989 only in Japan; it runs on Namco System 1 hardware, and was included in the "Encore" edition of the Namco Museum series for the Sony PlayStation (along with a second one of the company's Japan-exclusive games, their last 8-bit arcade game Wonder Momo - which, like this game, used a Yamaha YM-2151 FM sound chip for its songs). It was designed by Akira Usukura (who'd also designed Splatterhouse).

Introduction
The player must take control of Chap, a gardener who must collect all the keys in sixty-one maze-like gardens, in order to rescue his girlfriend, Rumina; he can push the walls in the gardens over, to crush the various enemies that pursue him, but they will immediately be resurrected in the form of eggs that hatch after a few seconds. Each round also has a preset time limit, to ensure that the player does not dawdle - and once it has run out, a green-haired female vampire known as Tsukaima (who cannot be crushed by the walls) will appear in search of Chap's blood as the music (and the enemies) speed up.
