We'll see - the game's made with Adobe AIR and Stage3d, and Adobe's dropped support for Linux which is why I don't mention it. You will be able to play the game through Chrome using their pepperflash plugin but that's not exactly a "Linux version". Hopefully there will be a better solution by launch time because I reaaaaly want to support Linux, but I can't promise it now.
Similar story for the Windows Phone: Adobe AIR doesn't support it, so neither can I. Also Android phones with Intel CPUs like the Motorola RAZR i. Please go bug them about it in the Adobe forums: http://forums.adobe.com!
