Use the arrow keys to move, If the player is online the number in the active box will change to 1. Press t to type chat. It will, annoyingly, make both players have to talk. Just press the tick if you don't want to talk. If you are the third person to join in, you will be kicked. I will play every so often. If you can't move, press the quit button and restart. Don't use the red octagon to stop the game, use the quit button.
I used cloud variables, the new thing on scratch.
