Ancient-Red-Dragon: Hollow Knight is definitely too hard and poorly designed as well.
It should have a Quicksave button and also a Quickload button, either and/or both of which the player is free to use at any time they feel like.
And it also should let you know with an on-screen indicator whether or not you have the gear necessary to pass through the current zone you are in.
What you are "missing," OP, is that Hollow Knight is a vastly over-hyped, over-rated game that isn't anywhere near so good as most people would have one believe.
The indicator would be appreciated for sure, if not visually at least through some NPC warning you with subtle hints.
In general I believe that taste in games is subjective. Yes, there is lots of praise and hype for Hollow Knight. It's just that many people who enjoy (and promote) it might come from a Dark-Souls-y background, thus being accustomed to such gameplay.
