Somnum - Wishes Woven in the Dark Labyrinth

A dungeon-defense RPG where you play as the administrator of a labyrinth. Rather than exploring, you set traps and deploy monsters to repel waves of adventurers trying to reach the core of your dungeon. You expand and fortify your maze to prevent intruders from reaching the innermost 'Labyrinth Nexus.' The game inverts the typical RPG formula—you are the dungeon itself, managing defenses against incoming parties.
