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 contemplative mystery where you uncover a ghost's past through careful choices, with a somber and introspective tone.

What players say

Players praise the complete, emotional story and true ending, with many calling it a tearjerker. The branching paths require trial and error, and some find the flag system frustrating. It is not a horror game despite the premise. Reviews are split on length, calling it a short story that feels complete.
