Understandable. Again, Sclerosis is a lot of hard work you're giving away for free. I can imagine you'd have cold feet about doing it all over again. But if I were you, I'd approach Frictional. They stand to gain from a partnership with you, as they could outsource to your team the project of remastering their older games as VR supported titles in the Unity engine, without taking time out from developing their new game projects. In their position I would find such a proposal very enticing.
