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 Viking army manager that grows stronger even while you're away, rewarding incremental progress and strategic upgrades.

What players say

Players finish the game in 2 to 6 hours, with many saying the fun ends after hitting level 1000. The idling is simple and relaxing but lacks challenge. Performance drops heavily as item counts grow, and the AI-generated art is a common complaint. A solo developer made it and there is no way to report bugs.
