Ghoul Thrasher

Ghoul Thrasher is a randomly generated Game Boy dungeon crawler that throws you into the deadly, monster-infested Citadel Sinystera. Once a lowly peasant, Gnargoth is now the last hope for the Squalid Swamp, a land overrun by monstrous abominations. The brave warriors are gone, and the townsfolk live under a reign of terror. It's up to you to lead Gnargoth through their perilous quest, to battle monstrous foes, and restore peace to the corrupted Citadel.
