Hi,
I'm a Unity3D developer with an experience of over a year and half in game development, especially in 2D. During this period, I have developed and published 3 games and another project is on-going. They are published in Playstore, iTunes store and Windows Phone store. I have also competed a Freelancer project here and it will be published very soon.

As I have mentioned, I will be using Unity3D for the project. I'm programming mainly in C#. Unity3D supports a lot of third-party plugins like Facebook, AdMob, Google Play Games etc.
I believe Unity3D is the best choice for your game project. It also supports building into number of platforms.
