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 strategic solitaire game wrapped in a fuzzy, ominous 90s CD-ROM aesthetic that feels like uncovering a forgotten relic.

What players say

Players say it is a short and easy solitaire game with a campy 90s PC aesthetic and a light story, comparing it favorably to Inscryption though simpler. The meta jokes and Satanic Panic framing charm many, while a few find the gameplay too shallow and the price too high for its length.
