READ BEFORE PLAYING. Sorry but I have to tell you this, there are a few glitches, so here are a few ways to avoid them: never press green flag when in middle of a game, when you are looking inside, turn off before going to project page. Also I am adding comments inside so this project can help people who want to make a multiplayer game. If you want to see variables go in and checkmark them. If you have any idea for code that notices when a player clicks green flag in middle of game, post in comments.
I give credit to pizzakingmister for running tests with me.
