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-on, experimental sandbox where you methodically balance plane parts and physics to build functional aircraft in a colorful, open world.

What players say

Players praise the satisfying building and flight physics but consistently ask for more campaign missions. The game is calm and addictive, though some find the campaign too short and note missing features like Steam Cloud saves and HOTAS support.
