Same, thankfully you can speedrun the game in like 3 hours when you know where to go and what to do (there's an achievement for it too)

Oldschool games man. Gotta love them. getting to a point-of-no-return is very common in these. I'm at the point were I got brutalized in the Demon Realm, I have only a tiny bit of health and no herbs or medicine. I might not be able to beat it XD

Like most game, there are always a "point of no return."

I suggest playing this game with at least 2 other saves and your main one, since there's quite a bit of missable things that you can't go back to get them, such as the power jewel in the beggining and also the magic jewel after you get the bow.
My suggestion is: if you never played it before, play the game normally without using any guides. But after beating it once, start another playthrough but this time following some achievement guide or anything like that.
Also after you know where to go, you can beat the game pretty quickly (I finished it in less than 2 hours in Ultimate mode), so this won't be a big problem.
