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 methodically scan a dark, abandoned apartment with a handheld device, piecing together subtle anomalies in a quiet, tense atmosphere.

What players say

A short anomaly-hunting game where you spot differences in a repeated apartment floor layout. Players praise its forgiving punishment system, missing anomalies only sends you back one floor instead of restarting. The scares are effective but not overly violent, and the game respects your time with a 40-minute to hour-long playthrough. Some wish it were longer.
