Rompers

In Rompers, the player controls farmer Chap, who is trying to save his girlfriend Rumina from Gurein and Tsukaima (a man and his succubus, respectively). It is a maze game with 61 levels, filled with enemies and keys. The goal is to collect all the keys. The only way to destroy enemies is to push over the maze walls to crush them. However, they respawn. When the timer runs out, Tsukaima appears, who is invincible, and the enemies' speed increases. Once all keys are collected, the player can progress to the next level.
