I wasn't able to load the game either at first. But when I removed "?tab=achievements" from the end of the my url and refreshed the page, it worked fine.
I played this game once and liked it a lot. Then I played it again (for the badge) and noticed the differences had changed slightly. A replayable difference game this beautiful deserves 5 stars!
