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 first-person interactive narrative where you play as a baby with immense privilege in a comedic, story-driven world governed by a benevolent AI.

What players say

Players are split on a game they find deeply confusing and abstract, with a nonsensical plot about an adult treated as a baby by two women. Some appreciate the artistic ambition and strong actors, while others call the experience a boring fever dream and criticize the broken translation and frustrating Q&A mini-game.
