Hello, How are you ?
I am a mobile game developer.
I think you want to create addictive game like flappy bird game :-)
I can make your game perfectly.
Really, I can make simple game in few hrs.
I have created many mobile games and cloned flappy style game many times.
(such as flappy wings, Jumpy jack, flappy fall, hoppy frog).
These few months, piano tile game was one which was said to as flappy...
lol
I made that game first. :)
Now I am ready for you.
I will implement all your requirement.
Best regards.
Ri Jing
