About the game

Become a single spore on a journey to blanket the world in mycelium. Click to grow, unlock new mushroom species, and watch your fungal empire expand even while you're away. Whether you have 5 minutes or 5 hours, Fungi Simulator is the perfect idle escape. No stress. Just growth.

Original Steam description

From spore to sporemaster.

Start with a single mushroom. Grow it. Upgrade it. Then push deeper into the fungal kingdom.

With 4 unique mushroom types already waiting (and more on the way), each one demands 100,000 Spore Power from the previous tier — and doubles the challenge.

  • Click to earn spores

  • Upgrade your Click Power, Passive Generation, and Potency

  • Unlock new Fungi with escalating difficulty

  • Prestige and evolve for permanent bonuses (coming soon)

How far can your mycelium reach?
