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 stark, unforgiving puzzle-platformer where every move is critical and the only reward is the grim satisfaction of surviving a world built to break you.

What players say

Players enjoy mixing platforming with logic gate puzzles, calling it unique and educational. They find it challenging but satisfying, though many complain about jump controls feeling inconsistent and the game running heavy on mid-range laptops. Players split on whether it stays casual or gets frustrating.
