Build and Fly Obby

You cobble together a plane from whatever parts you have, then find out if it will actually fly. Each design handles differently, so some wobble, some spin, and a few surprise you by soaring. Fly through gates, dodge obstacles, and collect coins to unlock more parts, with every crash and successful flight pushing you toward the next experiment. It runs in the browser on desktop, phone, or tablet, using keyboard and mouse or touch controls, in landscape orientation.

About this game

Build a plane from random parts — and see if it can actually fly.

You are a mad inventor creating strange, funny and sometimes brilliant flying machines.
Every build is an experiment: some planes wobble, some spin, and some surprisingly soar perfectly.

Fly forward, dodge obstacles, collect coins and bonuses, pass through rings and gates.
The farther you fly, the more parts you unlock — and the crazier your planes become.
