The version in this link is heavily bugged asf.
Everytime you enter a new area, there's is a very high chance you LOSE everything, yes Literally lose everything (your level/exp, permanent stats, equipments, skills, money, etc.) doesn't matter how stacked your character is, you'll basically be regress to the very start of the game purely by chance.
Idk why it constantly happens, but even if you load back to a previous save its also the same (everything erased). I suspect it has to do with quick saving/manually saving just before entering a new area though idk that much programming to be confident in it.
