Preamble:
If you would like to obtain any of the software or virtual environments (Unity3D, C#) or simply learn more about them, please feel free to contact me. Depending on your project (for example, if you are a student and/or if the project is of social interest), I can help you modify the environment or develop it on another platform (mobile, Mac, Linux).
