🌱 Elevator Pitch

Mycelium: Old Growth is a botanical roguelike deckbuilder where players cultivate an underground fungal web on a 5x5 soil grid, root symbiotic synergies, tame toxic threats, and navigate seasonal quotas to survive into ancient Old Growth.

📖 Game Synopsis

Beneath the forest canopy lies an intricate subterranean empire. In Mycelium: Old Growth, players act as the guiding intelligence of an underground mycorrhizal colony. Every turn, spin a 5x5 soil grid to uncover symbiotic mushrooms, decomposing flora, mycorrhizae, and nutrient catalysts.

By locking key fungi into permanent roots, players evolve baseline species into legendary powerhouses with explosive geometric payouts. But as the seasons shift from Spring bloom to harsh Winter frost, quotas rise steeply, and hazardous threats—blight, drought, mold, and chemical pesticides—threaten to suffocate the roots.

With a 66-node Overgrowth meta-progression tree that expands strategic options rather than raw power, runs are snappy (12–18 minutes) and endlessly replayable.
