Fantastic idea!! I've been working off and on with local 4-8 player games, but I had only been using the Javascript gamepad API. I like how you're using smart phones, this seems like a good way to go about it!

It would be nice to be able to mix game pads and smart phones -- when gaming with kids, none of my kids have smart phones yet, so it would be nice to be able to let them use Switch controllers if we have those on hand, or use phones if we don't.

Regardless, I'm interested in this, and would be interested in contributing a game or two. This seems excellent!

You are able to mix gamepads and smart phones! Though there is a limit that you can only connect a maximum of 4 gamepads to a single session due to limitations with the JS gamepad API.

Would you be interested in also beta-testing our upcoming 3rd party game development SDK? If so, please ping me on our Discord (link at the end of the gamingcouch.com web page) so I can take your contact details for the beta-testing list :)
