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 gentle, low-effort desktop companion where you fish and decorate an aquarium while doing other tasks.

What players say

Players call it a cozy background game for multitasking, but note it needs frequent feeding and constant mouse work, so it is not a true idle game. A review highlights the forced always-on-top window as the biggest flaw, and one other player says the tiny size is a problem. Achievements are quick, with the 500 fish sale being the grindiest.
