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 casual, colorful tower defense where you manage cute monster defenders against robot invaders, with automated combat and light strategic planning.

What players say

Players praise the early-game fun and depth of monster synergies, but a persistent save bug that resets progress and a clear pay-to-win structure dominate the negative reviews. Many call it a low-quality mobile port with abandoned PvP and a paywalled speed button, leaving long-time players frustrated with unaddressed bugs.
