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 methodical, punishing dungeon-delving action RPG where grid-based movement and soul-crushing difficulty shape every encounter.

What players say

Players describe it as a strategic tile-based dungeon crawler more akin to puzzle games like Crypt of the NecroDancer than an action RPG or souls-like. The core challenge is planning every step and turn around lethal traps and limited movement, with death forcing a full level restart. Reviews note a short length of a few hours and a dark atmosphere with some camera issues.
