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 enjoy this as a casual incremental shooter where skill matters against enemy patterns. The variety of upgrades and large soundtrack are praised, though early stuttering was patched. Some find the first stage difficult due to progression tied to upgrades.
