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 soothing idle experience where watching marbles bounce and collide in natural physics is the main draw, with minimal effort required and deep passive progression.

What players say

Players call it a pure idle game where marbles auto-fire at targets, but lack of English support and buggy UI frustrate some. Long-time fans find it a relaxing zen retreat, while others say progression is slow and upgrades become imbalanced.
