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 disorienting, violent action game where a nameless girl awakens to a harsh, cruel fate.

What players say

Players praise the art, animation, and soundtrack, but many find the combat repetitive and boring with bullet-sponge enemies and long hallways. The gore is extremely graphic and central to the experience, while the story feels short and unfinished, with punishing saves that encourage slow play.
