How to Save Your Progress
This game auto-saves all your small progress (such as items, maps, defeated bosses) so you dont have to worry about losing progress.
It also does a “full save” (similar to hitting a bell) when you defeat the Harpy Fight. The reason for that is softlock-prevention issues.
However, if you hit a bell anywhere after that Harpy fight, that will be set as your new respawn point (as expected).
