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 tense, dialogue-driven experience that slowly builds unease through corporate language and policy, like a call you can't hang up on.

What players say

Players describe this as a short, unsettling choose-your-own-adventure horror game with a call-center premise. The voice acting and sound design are consistently praised, and multiple reviewers say it runs about an hour and is best played with headphones.
