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 fast-paced pixel-art bullet hell where you survive endless waves of monsters in dreamlike settings.

What players say

Players call it a capable Brotato-like with a large roster and a speed toggle, but sentiment is split: some enjoy the casual grind while others feel development stalled, leaving a shallow difficulty curve, no infinite mode, and imbalanced weapons.
