In this game you need to help a paper bird fly through the obstacles for as far as possible. The bird will fly to the right automatically, all you need to do is to control the altitude of the bird by clicking the screen. In some obstacles, there will be multiple places where you can pass through the obstacle, you may get a bonus score when you pass the obstacle at the designated place. The more obstacles you pass through, the higher your score. Each time you click, the bird will flap its wings and jump up, it will then fall down by the force of gravity, so you will need to click continuously. There will be obstacles so you need to time your clicks carefully to avoid hitting the obstacles. If you hit the obstacles, the game is over.
