FlappyBirdStyle does not work!

Good afternoon; I'm extremely frustrated. I lost my time! The example bird does not hold in flight and always falls. There must be something wrong with the GameControl script. I wonder if anyone could implement the game.

 

Is this from a Unity tutorial / sample project?
Maybe if you post the code you're using someone can assist you.

You haven't given us enough information to solve the problem. However flappy bird isn't difficult to make.

Here is a quick and dirty YouTube video I did showing the basic concept.
