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 deliberate, puzzle-like simulation where you design your own production lines and navigate trade-offs without prescribed solutions.

What players say

Players compare it to Shapez 2 and Factorio but note the tight space and resource constraints force constant refactoring instead of scaling. Many say the late game has excessive idle waiting because there is nothing to do once a challenge is done, and some report performance hangs near the end.
