Cmon, when I was playing it, and found some annyoing puzzle, first I was frustrated. But then I was like "Hey... wait... I'm here for 2 hours, and still can't solve this... It didn't happen to me in any RPG for years...OH MY GOD I LOVE THIS GAME". It was like all this annyoing RPGs I was playing when I was young, where you actually could get stuck, where you could look for solution for days. But when you finally found it, it was rewarding as hell, and you felt sooo proud of yourself. So much better than today AAA hand-holding crap, which even monkey could finish, pushing buttons randomly.
