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.

What players say

Players describe it as a zen idle game about feeding and growing koi, but many find the grind steep: fish take hours to mature, packs cost far more each time, and offline growth is missing. Opinion is split between those who find it relaxing and those frustrated by tiny, hard-to-see fish and a finicky interface.
