Stack Mates
Co-op puzzle platformer for 2 to 8 players, online and on one screen.

Overview
Co-op puzzle platformer for 2 to 8 players released on Steam in August 2026, with online multiplayer built on Fishnet alongside shared-screen play. Players shift between horizontal and vertical forms and stack on one another to reach the exit portal, and a level only completes once the whole team is through. Ten chapters introduce mechanics such as merging, sacrifice, reversed controls, flight, darkness and time limits. Owned the netcode, session flow, gameplay systems, UI and Steamworks integration; ships with full controller support and Steam Cloud saves.
