Thank you, I will keep that advice on hand for future cross platform development. I'm wary about my choice of C++ with SDL2 for my current project (not related to Tilengine) but it seemed like C++ had the most documentation & tutorials for SDL2 at the time I looked into it... I do want it to be cross platform in the long run, so I hope that doesn't come back to bite me...
