Thanks. Not sure why there's a save option in the menu if it doesn't work lol.
Yes, it's the old way of saving: the menu is grayed out and becomes available only when you're near a save point.
But I don't think it's clear enough for people who aren't used to old-school JRPGs, so I'm planning to change how it works in a later version to make it easier to understand and to be able to save freely in certain zones.
But for the moment, I unfortunately don't have any free time at all, so I can't work on this project.
