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-burning, unsettling first-person journey through a silent, oppressive environment where the horror unfolds through story and atmosphere rather than action.

What players say

Players praise this short indie horror as a solid first effort, finishing in about 30-60 minutes. It relies heavily on jump scares, which some find repetitive, but the atmosphere and story earn consistent compliments.
