I decided to make a not-really-game that was multiplayer. Then I thought "There are not many projects with cloud multiplayer, so why don't I turn it into a tutorial." The scripts for the red circle have comments on how to do it. red circle: wasd blue circle: arrow keys green circle: iklj
thanks @Will_Wam for your community chess, which inspired me to make a something multiplayer. (I worked out how to do multiplayer myself)
