I know it’s probably not happening extremely soon, but are there any plans to add multiplayer? How would it work?
Multiplayer is already possible (arrow keys+WASD), but online multiplayer isn’t 
There’s a difference.
I think it won’t happen because it’s way too complicated. You should better learn a real programming language (like c++) if you want to make an online multiplayer game. If you’re lazy, keep dreaming.
Sockets would be a helpful thing
