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 relaxed but gently relentless merge-and-hold loop where you shuffle slimes into place and watch a modest fence line snowball into a screen-filling swarm fight.

What players say

An idle merge game where you combine slimes, upgrade a fleet, and export items to trade on the Steam market. Many players report server and sync problems, including freezes, long merge delays, forced logouts, and version detection errors. Some call it addicting, others find the merge odds fake and the loop too repetitive, and a few say early NFT farmers were the only ones who profited.
