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 laid-back, incremental game where you repeatedly blast bugs, collect guts, and upgrade your base.

What players say

Players enjoy this short, satisfying incremental where you blast bugs and upgrade your ship. They praise the real build choices each prestige and the catchy sound design, but some wish there was more content and note the lack of settings for screen flashes.
