Currently this platform is available only for Windows (puke) or Mac.

More and more people are moving to Linux, however. Now consider this:

Based on Steam examination of statistics for gamers on Steam the OS breakdown is now this:

Windows 95% and slightly declining

MAC         1.91% and slightly growing

Linux       2;68% and slightly growing

So if you are willibg to code for the size of Mac you should be more than willing to code for Linux.
