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 rapid-fire 2D arena shooter with escalating horde waves and a focus on quick movement and diverse weaponry.

What players say

Players praise the retro arcade art style and unique weapon variety, but split on whether the game is a promising foundation with smooth performance and challenging fun, or a laughably amateurish and basic platformer shooter with not much content. Many request improvements to the aiming system.
