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 short, emotionally intense visual novel blending romance and eerie magical realism with a surreal, psychedelic edge.

What players say

Players praise the unique art, music, and emotional story, but note it is very short (around 3 hours) and includes graphic internal organs. Some say the male lead gets too much focus, and the bad ending is hard to get. One reviewer realized it is a retelling of The Little Mermaid.
