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

You explore a dark prison cellblock, solving cryptic puzzles while a supernatural threat looms, creating a tense and eerie escape-room experience.

What players say

Players praise the atmospheric prison setting and say the puzzles are clever and well-integrated with the story. The horror is slow-burn rather than jump-scare heavy, though some found it intense. A few report bugs like crashes or subtitle issues, and the game is short, around 2–4 hours.
