I have a Concept Art.
People are racing to make a clone of flappy bird that is as successful or close to the original. So I am selling my concept art that I personally think will work out well. Here it is tell me if you are interested.

I dont think that this would do it
Its worth a try, I mean the original was cheesy and dumb and somehow made it so why couldn't this possibly make it?

At this point Flappy clones are considered 'spam' on the iTunes store so I'd drop trying to clone it.
