Diamond Cat Studio, an independent development team based in Guangzhou, is developing ‘Ylem’s Cat’, an action-adventure game for PC via Steam. The game follows a girl named Molly and her companion cat, Mio, as they navigate the ruins of a dying planet to find Molly’s missing mother while being hunted by robotic beings known as Sentinels.

The gameplay features a “knowledge-unlock” mechanic where players progress by acquiring information and observing environmental phenomena or enemy behaviors rather than through numerical stat increases. A central mechanic involves Mio’s ability to change size and shape to assist the player in battle and environmental navigation. New details revealed at gamescom highlight that the cat features realistic behavior and that players can use bow reflections to interact with the animal, similar to a laser pointer. The experience emphasizes learning to fight alongside the cat to improve combat effectiveness.

Following its reveal at gamescom, the title has gained significant social media attention and gone viral. While the game has seen increased visibility, a specific release date has not been established.
