In Airplan IO, you get to fly super cool airplanes high up in the sky! You start with a tiny plane and zoom around, collecting shiny coins to get bigger and stronger. But watch out! There are other players in the air trying to bump into you! You have to dodge them and be the last plane flying. You can also collect power-ups that make you super fast or give you extra shields! It's so much fun to explore the skies and see how big your plane can get. So, grab your pilot hat and let's fly high!
