You don't do anything apart from click the green flag and enter a number. Then you can come back at any time and it will be the same. (You must have a save file - ask me for one if you don't in the comments.)
v1.1 UPDATE: The cloud variables are now working again - I can make you an account. UPDATE: I have now changed it to use cloud variables. Ask me for an account in the comments and I will make you one asap. For some reason, at the moment, I can't make any more cloud variables. Does anyone know why this is? ------------------------------------------------------------------------------------------ v1.0 It turns out that this only works for me and nobody else. I'll try using cloud variables and from now on ask me if you want a save file and I will create one for you. ------------------------------------------------------------------------------------------ This is a test for a game I will be making, so please comment and tell me if it works. This doesn't work if you are logged out or don't have a username. I have tested this - it works for separate computers and you can come off and on it as much as you like and your save file will still be there.
