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

You carefully manage a rundown castle, recruiting cute monsters and placing devilish decor in a laid-back, strategic simulation.

What players say

Players are split on this one. Fans of Kairosoft's build-and-battle games praise the monster collecting and room-building, but many call the balance rough: monster levels are slow to raise, traps do most of the damage, and adventurer strength scales faster than your own. Others note the screen gets cluttered and popups pause the game constantly.
