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 fast-paced bullet-hell shooter with lewd harem elements and lighthearted space opera feel.

What players say
Players enjoy the hand-drawn adult CG but find the shoot-em-up gameplay repetitive and slow, with little story and no upgrade system. Most recommend it for the art alone, though several wish for a gallery unlock option.
