While I was thinking of commenting about some sort of balm that heals more for cheaper outside of fights, I'd also like to point out the issue of someone can 'stop' exploring at any point and use it to somewhat cheat through the area - go halfway, stop, 'tent', carry on at full health with no downside
Especially if pausing and stopping became easier which I would like it to
Do agree making them much cheaper would throw off balance a little, could maybe reduce the scaling a little but it's a bandaid fix
What about an alchemy book or something - combining bought potions with found natural materials (such as the sand heart or whatever it was, from the desert, 70 health) to create either singular stronger potions, or a number of smaller potions although they restore more health
Just a thought, and requires more thought before implementing (if so- 3 enchanted leaves for one minor healing potion? more profitable than selling and buying, but less profitable than buying and making instead of just buying a minor)
I'd imagine the save issue was just it didn't progress far enough to overwrite - even if it's not rare, if someone's trying to restart anyway, lost progress for the first bit isn't *that* important
Anyway, good luck with development
