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

Set it and forget it: progress unfolds automatically through mythical realms with minimal input required from the player.

What players say

Players praise custom portraits but complain about punishing pet fusion with no skill lock, no battle speedup, and no cloud save, leaving progress lost to crashes. Content feels thin, and the lack of English and Korean support limits reach.
