 The game's enemies include white blobs known as , pink Triceratops-esque creatures known as which can breathe flames, armadillos known as which can roll over Chap, purple seals known as which can breathe ice, sponges known as , which can push walls onto Chap, turquoise blobs known as , which occasionally pause to take a long drag on their cigarettes, helmet-wearing creatures known as , which take two crushes to kill, wolves known as which can throw bombs at Chap, spiders known as , which can spin webs for Chap to run into - and this game's main antagonist, an evil scientist named who only appears on the final round, where players not only have to collect all the keys, but also push the walls onto his four clones (two of whom can breathe fire, but the other two can breathe ice).A cutscene called "The Rompers Show" also appears after every tenth round, and once Chap has rescued Rumina at the end of the game, they both go back to free Tsukaima (who, ironically, is trapped under a wall, given that she cannot be crushed by them in the game), and wrap her feet up with bandages; Chap then starts to carry Tsukaima off on his back, which angers Rumina as he went through a lot to save her.At the time of its release, "Rompers" was never ported to a home video game console, nor was given an official North American release, possibly due to one of the enemies, Fumajime Pyokorin, being involved in drug use, and the Japanese voice samples; the game's soundtrack was released in two compilation discs known as "Namco Video Game Graffiti Volume 5", and "Namco Video Game Graffiti Volume 6", which included soundtracks for other Namco games as well.
