Grow a colony of fighting fungi and keep the pests off the heart-root. Three acts, twenty-one waves, a new trail every act, and a boon after every wave. When the heart falls, the spores you earned stay behind for the next colony.
Build. Pick a fungus, then tap an open soil tile. Green-ringed rich soil gives +25% damage.
Grow. Tap a fungus to upgrade it twice, change its targeting, or sell it back for 70%.
Choose. Each cleared wave offers three boons. Bosses at waves 7, 14 and 21 offer rarer ones.
Keys. 1–6 fungi, Space sends the wave, U upgrades, S sells, P pauses, Esc cancels.
