I built the Linux version on a version of Ubuntu that fits on a thumb drive. It wouldn't even run properly but others said it was okay. I've no idea how Linux stuff works so perhaps it's similar to a Mac app where it's a folder full of resources.
I can't even get Linux to work on any of my machines any more so I'm afraid I can't offer anything else. The executable did nothing other than run the swf in a wrapper. So if you can play the swf you're playing the game - the exe or app version isn't any better.
