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 mentally demanding detective game where you piece together clues under the grim threat of nuclear terrorism.

What players say

Players describe a logic-grid deduction game where you analyze suspect movement logs like a detective. The randomly generated cases offer replayability, but many find the UI clumsy and tedious, requiring excessive clicking. The difficulty is significant: misplacing a single clue can force a full restart, and some puzzles feel illogical. Opinion splits on whether it is brain-burning or mechanical.
