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 hypnotic, minimalist idle game where you build a neon defense grid and watch cubes get crushed in a loop of progression and destruction.

What players say

Players split on Idle Defense. Some appreciate its mathematical depth and abstract feel, but many find it boring and repetitive, the game reskins the same enemy type six times with only health scaling. Mechanics are front-loaded rather than unlocked over time, which kills the sense of progression. A few warn the 3D graphics and confusing early setup are not what idle game fans expect.
