It's been forever since I played and it was on the Wii U version anyway. It's not just the boulder thing but lots of times where certain attacks would mess me up for a ton of hearts. I did get used to the game eventually and finish it but it's too obtuse for me
Maybe try to take a video recording when you get whacked. I can't figure out where (or how) you're getting instakilled on a regular basis
Just in general there are too many time I've been completely ganked for no good reason. Even with a decent amount of hearts I was getting instakilled regularly and it becomes very demotivational.
Replaying this for the third time currently👌
Same with other games. Nintendo had a big spike in sales at the turn of the year with the new oled model being released and Xbox and PS5 still difficult to get a hold of. That'll be how they justify it.
