Click the green flag and wait for the project to connect. Once you are connected, you can move around.
This is for making a version of Agar.io that I thought of in my head. 5/26/16: added inactivity timeout detection 5/25/16: added another cloud variable that detects if a person is on the project or not, making connection time much faster if there are less than 16 players on the project. Also fixed a bug after.
