(This would be my first time exporting and uploading a game. What do I need to know? How can I be sure my file is playable? Do I need to delete my test saves, or will RPG Maker MV not process those when exported? Thanks in advance!)
I have RPG Maker 2003 rather than MV, so I am not too sure as to how it works exactly, but, I would recommend to of course play test the game after "exporting" it, on multiple computers if possible, as well as checking through the files to make sure no saves are left over. Of course, I don't have MV so I wouldn't really be too sure.
