A free app for Android, by xinyou.

Do you want to play a challenging and exciting game and enhance your eye coordination using your mobile device? Then this game is waiting for you to take the challenge. This is the Flying Face game for Android. This is a fun pixel game, regardless of its simple form but extremely difficult. It has a simple but not rough pixel picture, a cute-looking bird, and a few white clouds. 

You need to use the camera app to control the frequency by blinking your eye to adjust the flying height and landing speed of the bird so that the bird can smoothly pass through the pipe gap on the right side of the screen. If you fall or the bird accidentally touches the pipe then the game is over
