Hi, we are developing a multiplayer web-game, which could be accessed via web page. How should we submit it?

We can create a dedicated server package which could be run on any machine and anyone would be able to connect to it. 

But it would be better, if we could also provide a link to already running server in internet, so people from different places would be able to play together. Is it allowed during submission?

Hi there,

I might be able to offer some advice. Can you share the URL for GitHub repo(s)? and the URL where the game is currently running?

Perhaps the front-end game be hosted on itch.io and communicate with the external server? We'll figure something out :)

Cheers,

As an option, use index.html with iframe. It's works for us.
