Thank you for the detailed response. It's very informative. Unfortunately, I do not currently have any plans to support Linux. My focus is 100% on new features, balance, bugs, and shaping the actual gameplay right now. We are still very early in development, so there is a lot to do.
I will evaluate cross platform development as I reach each major milestone (Alpha, Beta, Final), but I wouldn't expect anything before Final, which is quite a ways off. Sorry I don't have better news!
