The link is a 404 Error.

For what it's worth though. I went to the homepage and it does seem like a really nice product that a lot of effort was put into. When I saw game maker I didn't expect to be as impressed but it seems far better than the other web based game makers I've seen.

Although it requires the absolute latest Chrome (I was half a version back) which is interesting. I wonder what is in Chrome 57 that is required and not in Chrome 56.
