It's a bit scary at first but once you figure it out it isn't so bad. The main thing is that the aspect you want to edit (level, money, # of an item, etc.) will need to be unique to itself. For example, if you want to set your level very high, you won't be able to distinguish it immediately because a lot of things start at 1, but once you are level 7 or so then you can scroll through the pages til one of the green numbers is 7, click it and change what you want, download the new save at the bottom, and replace the save in the files. Hope this helps!
