Hi,
I'm trying to submit an html5 multiplayer game (io game). My problem is that I just can't upload our game files, because we run our own servers where always up-to-date client files come from.
Is there any way to submit such a game?
Thanks, Endre

We don't really have official support for games like these. What parts of itch.io would you like to use? Are you trying to collect payments, or get your game listed in our index?

You can upload an HTML file that simply contains an iframe pointing back to your original website.
