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

Building custom bunkers to client specifications feels methodical and satisfying, with a calm focus on precision and contract fulfillment.

What players say

Players see a detailed building simulator with genuine potential, but the early-access version is held back by bugs, crashes, and repetitive, overly guided tasks that can hard-block progress. The developer's quick community support and future plans keep some players invested, while others abandon the game for its unfinished state.
