I made this online Movement test using cloud variables without looking anything up. It has bugs if you have more than 2 players, and the y-axis takes a long time to update for whatever reason. for a first try at making multiplayer without looking anything up, it's not awful. If you know how to make the y-axis update like the x-axis does, please tell me in the comments, or remix this project.
