To be honest I have no idea how building a game for a non-Windows OS works, nor do I have a Linux system that I'd be able to test said build on. Aside from that, there hasn't really been enough demand for a Linux port to make it worth the work I'd have to put in. Down the line porting to other OS's is something I'd like to include in my future projects, but I think that ship has sailed as far as Cookies goes.
