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 calm, low-pressure experience of decorating an aquarium and watching fish swim to gentle lo-fi music.

What players say

Players describe Cozy Aquarium as more of a diorama builder than a fish game, since fish don't need care and there is no breeding. The appeal is the massive number of decor props, though some find them mismatched or surreal. The integrated pomodoro timer and to-do list are quirky extras, but some players report the game crashing on launch or never loading.
