Hi. I downloaded the game and played for a while. And I can make such game for you within 5 days. Also I will provide extra features such as Facebook integration (post and screen shots), Twitter integration (post and screen shots), Google play services leader-board WITHOUT ANY EXTRA COST.
Apart from all that I will provide 2 months free service, like if you want to get some feature added like powers etc, and in case you want to understand how the code works, and publishing the game on Google Play store.
Kindly give the project to me.
Thanks :)
