Nine hidden worldsDig from the soft Loam through the Rootways, the Clay Beds and the Glow Grotto, down to a drowned lake, a singing geode, the bones of something enormous, and the warm Ember Deep. At the very bottom, the Heartseed sleeps.

Small, strange neighboursEarthworms, dung beetles, glowworms, cave newts, crystal snails and fire salamanders move in as your web reaches them. Each world adds a new resource and a new way to grow: fireflies to catch, pearl beds to harvest, a geode that sings louder the faster you click, old bones that remember, and a kiln that bakes Heartfire.

Choose a gift at every cap level. Find 18 curios that the beetles dig up. Bramble, an old toad with a dry, warm humour, keeps you company.A real endingUnderbloom is a complete game. Your first forest takes about two to two and a half hours. When you wake the Heartseed, the dawn comes and the credits roll. Then you can keep playing, start again, or Replant. Mouse, touch screen or gamepad (full Steam Deck controls).…
