I'm a long-term, professional developer (18 years - multiple programming languages) with the last 6 years specifically in game development. As lead developer for a small, indie game development (Misfits Attic, LLC), I have 2 released titles for sale, which can be found on Steam: A Virus Named TOM (written on the now defunct XNA engine, as well as ported to C++ for the PS Vita, where it is also available for sale) and Duskers (Unity 5.3.4f1, Pro). Both were primarily written in C#. I would love to help you to complete your game, or even jump in from the beginning and lead development!
