EDIT: After finishing 86% of the game and 3 of the 4 endings: It is extremely difficult in some places. But it still is a great game. For one boss I needed 60ish tries, roughly 4 hours just for that boss. I never do stuff like that in games, really never. I gave up Dark Souls after I think 4 bosses, I gave up on Sekiro after getting pretty far. But this game is so good that I really wanted to finish the "true" ending! Original: It's clearly not an easy game. But I'm not a Dark Souls player. I've tried several times to get into those games, but never managed and got super annoyed by them. I've finished Hollow Knight though. And I intend to finish Silksong. Maybe not 100% of it, but the story. I'm at the end of Act 2 now, so I'm close to at least one ending. During my game I always used the way of least resistance: If there was something I couldn't do, I started exploring the areas that I could and usually found skills or tools that made the other challenges easier. Or I just got better by doing the exploration, I'm not sure. There's some things that where annoying. By far the worst one: The trapped bench! Unnecessary, unfair and not fun. Some runs to bosses could have been shorter. Overall still amazing how much game is in this game. So much to explore and find. Not a perfect game, but a great experience and worth the wait.
