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 relaxed yet strategic fusion of blackjack and roguelike progression, where careful number decisions determine each run.

What players say

Players are split on the fun factor, but the biggest controversy is the use of AI for art and music, with many calling it AI slop and devs allegedly lying about it. Those who enjoy it compare it favorably to Balatro, though others find it too easy, repetitive, and lacking content for the price.
