Thanks for your reply!
Tested - lol, I can connect via mobile / tablet, but not via pc.
Pc game loads in firefox, but not chrome.
Hm... i can launch it with chrome, opera and firefox. Is this happens only with my game?
Also I can't use multiplayer tickbox, so can only do tutorial (this is on mobile and pc and tablet)
Did you tried to uncheck tutorial, or just complete it? I've updated my project - now you can choose multiplayer without any trouble.
You will notice if you inspect page, that you have a ton of errors.
I enabled Developer Tools in Crome (F12), but i didn't see anything suspicious... Where i can see this errors?
