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 laid-back but engaging simulation where you mix ingredients and commands to discover new monsters and use them in tactical battles.

What players say

Players find the game charming but underdeveloped. The core loop lacks depth, money becomes useless fast, and there's too much waiting. Bugs are a persistent issue, including a game-breaking menu crash and frozen interactions. Community sentiment is split: some enjoy the 10 hours of content, others warn updates have stopped, calling the project dead.
