I saw Alex speak at a Unity meetup in San Francisco on October 17th of this year. He demoed Code Hero, and (I thought) he said it was available for purchase. I thought he came off as passionate about the project. I wasn't convinced that this would necessarily be a good way for noobs to learn programming, but nevertheless I thought it was a pretty impressive demo. Just my 2¢. (I'm not a kickstarter backer of the project, and this is the first I've heard of these allegations.)
