Hi,
I have an experience of over A year and half in game development, especially in 2D. In this period, I have developed and published 3 games. The games were in Android, iOS and WP8 platforms.
Although you mentioned to develop in Game Salad, I think I can work out the project exactly as you prefer in Unity3D engine, which is more flexible and powerful than Game Salad.
Tools:
---------
I will be developing in Unity3D engine. I'm mainly programming in C#.
Method:
-------------
I'm able to provide you demo on each developmental stage, but that is entirely your choice. I'm not a designer, so you will have to provide me with the graphics.
For further discussion, please feel free to contact me.
