For the record, I didn't enjoy Hollow Knight much either. It felt too repetitive and difficult to me...
That is the same conclusion that I and my brother both came to. The game is bizarrely punitive, from the very beginning, for no reason. It's as if they thought of it as being the next Hollow Knight expansion after Godhome, providing an additional challenge for the people who have beaten every pantheon with all bindings. ("The new challenge is: all of your controls now do something different!")
But it's a sequel. Supposedly. Most sequels are aiming to appeal at least as much to players who enjoyed the first game as they do to a hypothetical new audience.
Some discourse makes it sound like we're thrown 20 hours into HK at the beginning of Silksong. I know I'm biased as someone who beat 100% of Hollow Knight (granted, there's 112% of completion, so I did not in fact beat ALL the content), since I've played more HK than average.
Like those birds that will always mirror your movement to stay just out of reach, move erratically otherwise so you're guaranteed not to get a hit in (forget about hitting them with your spear when they're in the air), and just when you managed to get under them where you might be able to land a hit they'll drop down on you to deal contact damage and flutter away again.
10 hours in, and I've not even started the game since Saturday afternoon, when I was expecting not to be able to drag myself away from it (being a huge fan of the first Hollow Knight).
