Build and Fly Obby

In "Build and Fly Obby," you're a mad inventor crafting unique planes from random parts. Every build is an experiment: some planes wobble, some spin, and some surprisingly soar perfectly. Select items from your inventory and tap on the plane to add parts. Control your character with WASD or arrow keys to move, right-click to rotate the camera, and space to jump. On mobile, use the joystick for movement and swipe to rotate the camera. Fly forward, dodge obstacles, collect coins and bonuses, and pass through rings and gates. The farther you fly, the more parts you unlock—and the crazier your planes become. Enjoy features like free plane building, unique physics, multiple biomes, funny crashes, and progression records. Experiment, crash, improve—the test is never over.
