I'm really excited about the better mobile support. I wonder how my game would look like on a mobile device. :)
I'm also excited about the .exe exporter, there are just so many new possibilities with it! I wonder if all current browser features will still work in the .exe export? (like post/request ajax, open new link etc.)
Well, I can't wait! The developer team is doing a great job! Keep up the good work. :)
