Reverse Flying Bird

Another clone of the original game, but the bird is going backwards, from end to start.

When the game begins, the bird will be at knocked state on the ground.
Now, the bird will get back up and "unhit" from a pipe.
You have to tap on the screen to flap downwards and navigate the bird through the pipes to the start.
--If you reach start position, you win.
--If you hit a pipe, you lose.
