Extreme plane is really hard. It looks simple, but it is possibly the hardest casual flying game in the world. You will have to retry many times. Touch and hold anywhere on the screen to fly up, release to fly down. Avoid the obstacles. Everything moves super fast so it is very difficult. You will have to retry many times. No flapping in this game, just try to survive. And if you crash, just retry. Yes, you'll be pressing that retry button many times.
