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, low-pressure idle game about buying, raising, and trading virtual jellyfish to gradually grow your collection.

What players say

Players enjoy the jellyfish theme and variety, but find the interface clunky: there is no bulk sell or lock feature, and settings lack a save button. Some say backgrounds clash with the jellyfish, making them hard to see. The game is compared unfavorably to Chillquarium in quality.
