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

You control a ball you can shrink and grow to shift its speed and weight, carefully solving physics puzzles while racing against the clock for medals.

What players say

Players enjoy the simple but tricky ball-size mechanic, finding the levels clever and the physics satisfying. Opinions are mixed on how engaging it is long-term, with some calling it a good background game and others finding too many levels boring.
