Ylem's Cat is a single-player action-adventure game from Diamond Cat Studio, a seven-person team founded in Guangzhou in October 2025. Molly, a young woman of the Endi people, searches a slowly cooling world for the mother who went looking for the cause of its decline and never came back. She travels with Mio, a black cat that saved her during the quake that birthed a new giant, and that can shift between three body forms. The design centres on knowledge-driven progression, where understanding how the world works is what unlocks the way forward. Built in Unreal Engine and announced for PC via Steam; no release date has been announced.

Mio is the shape-changing cat that accompanies Molly, with three switchable body forms, a stamina loop and behaviour that doubles as the game's hint language.
