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 meditative, logical puzzle game where you methodically place instructions on a grid to manipulate data, rewarding careful optimization of size, speed, and cost.

What players say

Players call it a solid Zachlike puzzle game about building stack machines to process numbers. Enthusiasts love the pure logic and optimization leaderboards, but some find too many repeating puzzles frustrating.
