I really like the game but gosh, fights are hard, way too hard for nothing, especially when it ends directly on a Game Over, with this save system. Even with enough potion found in hidden chest, I had to buy more and ended getting hard pinned down by enemies.
In the case you would have unlimited saves pretty much everywhere you want (I like the idea with the amulets and the Goddess Altars all around the maps, giving you free saves), I'd say actual fights are OK but at this moment, I think it's too much of a hassle for the reward, aka pratically 0 items and like 3-4% of level xp.
And since we cannot like sleep at home to get HP/MP back, you can softlock yourself without enough potion to regen and no money to get HP/MP back.
That's the only complain I would give, since the game is still in early stage and pretty much everything else is great, in the worst case "okay".
