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.

What players say

Players praise the unique particle-based art and soothing soundtrack, calling it a meditative puzzle-platformer with light exploration. The game draws frequent comparisons to ICO and Shadow of the Colossus, and finishes in about 6 hours. Some find the platforming and waiting frustrating, and the camera can be tricky.
