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 isekai premise and character designs, but note the art is AI-generated and the game has no animations. The story is described as short, around 2 to 3 hours, with multiple endings that add some replay value. Some players mention resolution problems on ultrawide monitors.
