The 3D catalog: game boxes on wooden shelves, with the cat sitting at the counter next to its greeting.

The catalog in 3D

The same catalog has a room you can walk around in. The cat behind the counter is the AI Catbot, and they pick real games from it when you tell them what you feel like playing. Nothing is for sale, here or in there. Go in from here and this game is already out on the counter, with more like it waiting on the shelf next to it.

How it feels

a slow, minimalist, and meditative experience where you explore abstract black-and-white environments at your own pace.

What players say

Players praise the monochrome art and dark atmosphere, but split on the exploration: some find its lack of a minimap and fixed camera tedious, while others enjoy the concise short runs. The story is heavy and morally grey, with most endings leaving no clear resolution.
