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, hands-on fish-keeping sandbox that invites creative relaxation while building and observing a peaceful underwater world.

What players say
Players praise the realistic fish behavior and the ability to breed fish. They love the axolotl and jellyfish DLC, but many want shrimp, snails, and more tank decorations. Some find the tanks too restrictive even in sandbox mode.
