About

Castle of the Zephyr is a spiritual remake of the classic roguelike Castle of the Winds. Explore procedurally generated dungeons and hand-crafted ruins, master spellbook magic, manage weight-and-bulk inventory, build your classless hero, and race against time to stop an ancient evil from awakening.
