I'm not sure how to use this SugarCube configuration for specific passages?
Basically I'm looking for an option that will allow a player to set a higher difficulty by disabling all manual saves, including disk saves. So to do this I could disable manual saving on my save game passages.
If I can't work out a way to do that, I can imagine doing a system where I use an <<if>> macro to completely remove the save/load game links and just replace it with a simple "load autosave" button using Save.autosave.load(). Which, come to think of it, is a much simpler way to handle things.
