Underdeep Jeweler Opens Free Demo for Steam Next Fest

Underdeep Jeweler, a 2026 indie play Best Design nominee, has opened a public demo for this Steam Next Fest. The workshop management game has players inherit the old jewelry shop "Crimson Hall" in the underground city of Fathomholm, picking rough stones, cutting gems and designing jewelry for clients. It layers Cthulhu elements and an "Awareness" stat onto the gamble-stone loop, with strange phenomena tied to the protagonist's missing sister.
