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 relaxing idle aquarium simulation that turns your desktop into a calm, meditative retreat.

What players say

Players say the game demands constant manual clicking to open boxes and collect fish, with extremely low drop rates and no pity system for rare items. The idle mechanics feel weak, and some report unwanted friend invites being sent automatically. Players are split on whether the game is relaxing or frustrating.
