However, I know that many people (like me) wish to share their creations in Arcade, but they cannot because the limits. I cannot upload my two games because both are over 10mb.
So, I suggest an option where I also can embed my creations in Arcade from other hosts. E.g.: I upload a game in Dropbox, copy the public link, paste it in Arcade, set the width and height, upload a picture and the site automatically adjust my game in an <iframe>.
I believe this would save space and traffic on the Scirra server, and we would have more freedom to show our work. Obviously, it would be necessary moderators to verify the games before publication (to avoid bad software).
Well, that is all.
