I don't believe Mamba's boxed retail release will contain versions for any OS other than Windows, so there wouldn't really be anything to screw up...er, unless they were to forget to put even the one Windows version on the disc. ;o)
Actually, I'd e-mailed the developer asking him whether or not there was going to be a Mac version on the disc. He replied and said that he wasn't sure. But the downloadable extended version contains no Mac application (and also no Linux version, for that matter). However, the game can be played, regardless of which OS you have, either through one's browser or through Adobe's standalone Flash Player.
