Rustil: Eternal Labyrinth Castle

Rustil, who has no memory of her past, is drawn to a vast labyrinth castle and sets out to climb its floors. The castle’s corridors and rooms change between expeditions, with monsters, treasure, traps, and bosses along the way. Combat combines attacks, dodges, guards, and weapon skills. Rustil can fight with swords, a magic staff, or a bayonet, while abilities gained from the souls of heroes let players develop different combat styles. Explore for equipment and items, then choose what to carry in a limited inventory. Monsters can be captured, trained, and summoned as companions. Persistent upgrades strengthen Rustil between runs; Safe Mode keeps found items after a failed expedition, while Challenge Mode risks carried items for improved rewards.

As amnesiac Rustil, fight through a shifting castle, shape combat with fallen heroes’ abilities, and capture monsters to summon.
