Mars Defender is going live on the Mac app-store. It’s also available directly from my website here, for both Windows and Mac.
There will also be an ” Xperia Play Optimized ™ ” version for Android soon, making nice use of the hardware D-Pad and Playstation buttons. I was actually contacted by Sony Ericsson to see if I’d work the game for this new platform, so hopefully a little exposure will come from it too.
