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 simple, arcade-like pseudo-3D shooter with visual novel segments, offering fast-paced wave-based monster hunting.

What players say

Players describe a short 3-hour visual novel with easy on-rails shooting. The story has sci-fi horror and yuri romance that some found emotionally impactful, though others say it is underbaked. Most agree the gameplay is simple but the presentation and music carry the experience.
