Unfortunately, such would require a major rewrite of the whole game that I'm not really bothered to do for something I made in two weeks.
Going off playing the game with my friends, the main issue seems to be connectivity; sometimes the servers are down or overloaded, but we did find that if one player is trying to connect through the download version and others are trying to play on browser, the games wouldn't connect, although I have seen a few YouTubers play the game fine like that, so maybe I'm wrong.
