Just make sure that older saves, like on older maps that you arent carrying over wont bug up stuff.
Like lets say you tried to load a map from Chapter 1, which was maps 1-10 into chapter 2
You, the game maker, forced me to save on map 10, and carried that over to Chapter 2, making chapter 2 maps 10-20.
What if I had a save from map 7?
If I tried to load it in the chapter 2 game files, it would bug up.
It works if you restrict menu/save access in your game.
If not, then stuff might get messed up.
