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 build and tinker with simulated physics and artificial life at a particle level, experimenting with rules and observing emergent behavior.

What players say

Players enjoy a true physics sandbox where they can smash things together and find it highly addictive, though they report a rough UI and performance problems on AMD hardware.
