Zup! Q

Zup! Q is a self-contained casual puzzle game from Quiet River that launched on March 8, 2023 with 60 levels and a defined set of features (physics, portals, lasers, achievements). The store description presents it as a complete, fixed package with no mention of planned updates, additional content, or post-launch support. There are no DLC listings of any kind. The developer news posts from this game's page are announcements of entirely separate, new games the studio has released (Only Down, Cube0S, Zup! Y, a horror game, and OxU 2) — a pattern consistent with a small indie studio that releases standalone titles rather than updating existing ones. None of these posts reference returning to Zup! Q to add content. Zup! Q appears to have launched as a finished product and remains so.
