◆What is 'Mushroom Legend: Hero and the Magic Lamp'?
A super exhilarating idle RPG starring mushrooms. 100 years ago, a hero of the mushroom tribe fought a fierce battle with the Demon King, and at great sacrifice, the goddess sealed the Demon King with the power of a magic lamp, and the hero also fell into a deep sleep. 100 years later, the Demon King's seal is about to be broken. The hero, awakened from a deep sleep, uses the power of the lamp left by the goddess.
