Quench Forge is the developer and self-publisher of Ultimate Blacksmith Tycoon. The store page describes it as “a solo planner/PM working alongside an AI development team”, and a Steam post by the developer calls it a one-person studio. The studio site describes an independent studio in Japan and lists seven games, among them FLOWORKS, OUTWORKS and ALGO ARMS.
A numbers-heavy blacksmith tycoon: appraise materials, bend the rarity of every blade you forge, and send hired adventurers into dungeons instead of fighting yourself.
