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, idyllic screensaver-like experience where you simply watch a serene underwater world drift by with no pressure or complexity.

What players say
Players use this as a desktop decoration or sleep aid, not a game with objectives. They appreciate the beautiful visuals, ambient sounds like rain and cat purring, and music, but note it has minimal interactivity, you cannot choose or decorate fish. Some long-term players complain development stalled and widescreen support is missing.
