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 hands-off, hypnotic loop of automated carnage where you watch your swarm mow down endless enemies with satisfying feedback.

What players say

Players describe it as a chill, idle-friendly survivor-like where you defend a central point and can enable auto-pick skills and up to 4x speed. The loop is satisfying early but runs out of variety around 10-20 hours, with some saying replay value is low. Performance holds up even with large enemy waves and speed boost enabled.
