About the game
Grow an ever-expanding fungal network in this relaxing incremental exploration game. Discover hidden resources, cultivate mushrooms that automate your production, and evolve your mycelium into a self-sustaining underground empire.
Original Steam description
MYCELARIUM IS A MEDITATIVE INCREMENTAL GAME
Start with a single mushroom. Spread your mycelium through the soil, discover hidden resources, and build a thriving underground network. Automate resource production, unlock strange new mushrooms, and watch your tiny organism grow into a vast, self-sustaining fungal empire.
The forest is alive, but not hostile. Leaves fall and decay into food. Hedgehogs wander across the surface. Trees can become future sources of nutrients. There is no rush and no hard fail state, only the quiet pressure to expand, adapt, and connect.
Explore an endless procedural underground filled with food pockets, water reservoirs, hard soil, and impassable stone. Build your fungal empire one thread at a time.
