Seems impressive, congrats! How long did it take from start to finish ? How many people were involved ?
I was the sole game developer / designer working on it. It took about 2 person months of effort. I have prior experience in Java and Libgdx engine. But this is my first in Unity3D and C#. Along with Unity3D, Google Game Services and OpenIAB plugins have been used. I used Blender for 3D modeling and animation and GIMP for 2D image editing.
