The Heartwood ❦ is the last living heart of this forest. Every night the Blight crawls out of the rifts ✶ to devour it. If it falls, the forest is lost.
By day, gather. Look down and tap E to pick things up; hack plants and trees with the machete LMB. Hold E to search crates, packs and caches.
Mind the weight. Your satchel carries 20 kg. A heavy pack slows you and is heard from far off. Bring the haul home and store it in the Coffer by the Heartwood. Fall out in the forest and your pack stays where you fell.
Craft at camp. Open your satchel with Tab. Towers and walls are made at the camp's benches and draw on the Coffer; traps and healing can be made anywhere.
Build around the Heartwood. Pick a defence on your belt 1–8 and click to place it on the paths from the rifts ✶. By night, fight beside them. Hold ten nights and the Heartwood blooms.
