Thank you @Tezliov! They made a tutorial on how to make a simple multiplayer game! Go check it out at: https://scratch.mit.edu/projects/20179538/ It is very clear and has examples to answer your questions! Make sure to give it a love and a like! To play, use the arrow keys to move. If the other player is not moving, then it means no one has joined you. You can only move once the number in the top stops being 4. So far only two people can play at a time! Sorry! You will get kicked if you are unactive!
