Okay Okay, so there was a slight mistake in the posting last night. I apologize, we are releasing the prototypes in Chrome(with good reason), but of course the real game will be available on all platforms. There is an alternative to using Google chrome. But don't take my word for it!
Have a listen to one of the guys that helped create it, along with Scott and Mark later in the audio.(This is podcast episode 4 by the way)
