Simply wait 3 seconds for the game to start. When game starts, press SPACE to fly upwards, otherwise you will keep falling. If you hit the pipes or the floor, the game will be over, and it will restart again in 3 seconds!
I'm sure you all heard of flappy bird, and I bet most of you have played it. But now, it has been removed from the app store, so if you never got a chance, here it is, but of course it isn't as good. All the credit goes to the guy who made flappy bird.
