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 quiet, reflective email-based narrative that unfolds slowly, with a melancholic sci-fi backdrop and a focus on personal loss.

What players say

Players praise the beautiful art and music, but split on the story: many call it a touching emotional experience about grief and AI, while others find the writing stiff and object to the 'replacement lover' premise. A male friend character, K, draws strong disagreement, some see it as an unnecessary intrusion on a lesbian story. Short at 1-3 hours per run, with multiple endings and a meta layer.
