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 mix and stretch ingredients in your own lab, experimenting freely to create custom slime with a calm, hands-on feel.

What players say

Players praise the slime physics and smooth VR performance, but many find the experience shallow and tedious after the first hour. The game is compared to a tech demo with limited depth, and there is no support for non-Meta headsets.
