Immortality Factory is a single-player simulation game in which players build and automate a factory to unlock new machinery and recipes, focusing on idle gameplay mechanics. In this game, you start as a former apprentice expelled from a magical realm for your interest in forbidden immortality magics, and you must forge your own path in a cursed valley filled with potent magic and cursed knowledge. It stands out with its pixel-art style, emphasis on automation, and progression through unlocking increasingly complex machinery and recipes, blending magical themes with strategic factory management.
