peterb: A Tale in the Desert has been released on multiple platforms (Windows and Linux) with more on the way. How early did you decide to go multi-platform? Did it impact development?

Andrew Tepper: We did it immediately, so right from the start we did things like separating the rendering code so that in theory there was one file that needed to be changed to go to a different platform, or to a different graphics API (openGL to DirectX, for example) and then a single #ifdef to change to a system that was different byte order. In practice, it worked pretty well. There were a few bugs, but it's been pretty easy. For the most part there were just a half dozen or so bugs where we made assumptions about byte order...the whole idea was that stuff that hooks in to the operating system is isolated. It was pretty clean. The Linux port took about 3 weeks. And the Mac port has been underway for about 5 weeks.
