Thanks for your reply :)
The reason I need to use separate games is because I would be producing a new level each day and only want to upload that particular content and the menu it self.
So, every day I would update the menu to show more icons, and upload the new "game/level".
The second reason I would like to use multiple files, is to stop people from taking the game as a whole, from my site.
Since html 5 is easily copyable, I though this would be a good way to do it as the level files would each be named randomly and no one would bother to hunt down all the files ... or at least it would make it harder for them.
I'm not set on this solution, but I don't really have any other ideas on how to make sure the game doesn't get taken from my site.
If anyone has any other ideas, that would be awesome :)
