You can contact support and ask for an exception, but it this is a web game, you really should try to make your game use fewer files, because a lot of people will have trouble loading and playing it.
I dunno how to make it with fewer files. i know that from 500 to 686 isnt that much more files. the 500 is kind of a recomendation. i saw that admins can rise up the limits. how can i contact support?
