Underground Spirit
Cozy cave colony builder
Free · Designed for iPad. Not verified for macOS.
Guide glowing wisps through the dark. Dig tunnels, raise a quiet colony and wake an ancient Spirit Tree. Every colony is a newly made underground world.
Deep underground, an old Spirit Tree has gone dark. What light is left gathers in one small spring, and from it a single wisp wakes.
Underground Spirit is a calm colony builder set in the dark beneath the ground. You don't steer the wisps one by one. You mark the rock to dig, the moss to gather and the places to build, and the wisps sort out the rest: who goes, which way, and what to carry.
DIG INTO THE DARK
Every colony gets a new map: around twenty caves, cold and hot zones, crystal veins, clay seams and stands of cave trees, all hidden in fog. Only digging lifts it. Far to the east, something glows amber.
GATHER SIX WISPS
Three wisps rise from the Wellspring. One sleeps in crystal in a far geode, and two wait in springs that ran dry long ago. Each has a gift. Mica digs faster, Sol doesn't mind the heat, and Vesper never sleeps. They earn titles as they practice, go to bed at night, and have favorite spots where they like to sit.
BUILD WHAT KEEPS IT GOING
Raise resonators to draw crystals from the deep, Rosniks to grow food, clay springs, hearths against the cold, nests, lanterns, and light bridges over the gaps. Lay root paths for quicker walking, and upgrade buildings until they run on their own.
WAKE THE SPIRIT TREE
Find the tree and bring it back in three phases. Once it stirs, rot creeps out of the dark at dusk and at night. Purify it, raise wardstones, and break the blight hearts at the center of the corrupted caves.
FIND THE STORY
Story stones, ember seeds, frost blooms, spore caps and old tablets lie in the cave floors. Each new kind unlocks something, and the stones tell a story in twelve parts that you can reread in the journal.
