So I built up a new game and now get to the point where I need to use savefiles. Now what randomly crossed my mind is the question of how someone who isn't playing with a Byond account can save. The savefiles save onto the host's computer and when I've played Byond games the only way I have reset my saves is to logon to a seperate accounts.

So.....do savefiles only work if the player has a Byond key, or does their guest number substitute their key or what?
