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 habit tracker that feels like tending a low-effort virtual aquarium while being reminded to stay hydrated.

What players say

Players use it as a background hydration reminder with a tiny aquarium to tend to. They find it relaxing and useful for desk workers, but note the fish consume food too quickly, the aquarium can't be repositioned on screen, and legendary fish are buyable from the start with no level gating. Some report Chinese text display issues.
