    "Tiny Wings" is an iOS app created by Andreas Illiger which made its debut on the App 
    Store in 2011. It surged to the top of the App Store charts when Apple featured the 
    app in one of its Keynotes. In the game, the user controls a bird's flight, which is 
    determined by how well the user utilizes the hills to launch the bird into the air. 
    The game is a race against time, as it ends when the sun sets in the game.
