Obby Build a Plain
Obby Build a Plain drops you into a world where everything depends on your hands and your ideas. You don't just run around the map; you build your own flying machine step by step. Collect blocks, grab parts, and decide what your plane will look like. Pick what the body is made of, choose the wings that work best, and don't forget about the engine. As you progress, the parts get better, and you can be more daring with your builds. Want a fast little jet or a massive heavy plane? You can pull it off if you stay accurate and keep going. In this obby-style arcade game, the goal is not just to put a plane together but to refine it so it takes off and holds steady in the sky.
You run across platforms, collect resources and parts, then use them in your workshop. Jump across blocks, hunt for rare parts, and try not to fall, because one bad step can cost you part of your progress. When you've collected everything you need, head to the build area, install the wings, engine, tail, and wheels. Then launch your plane and see how it behaves in the air.
How to play?
Test different setups by swapping parts, reinforcing the body, and finding the right balance so the plane doesn't flip over. The goal is to build a stable plane that can fly to the end of the level without breaking apart. Good luck, pilot-designers, may your plane fly higher than all the others.
