Silksong expands on the world of Hollow Knight, as well as the movement and combat. I loved Hollow Knight for the exploration, the rich and interesting world, and the comfortable movement mechanics when exploring that world. So, being in a new kingdom with new enemies, bosses, areas, music, items, and mechanics is very refreshing and was an incredible experience.
I think that, in expanding on these things, Silksong is technically a better game than Hollow Knight, though I prefer Hollow Knight. I will spend the rest of this review explaining why I prefer the first game over this sequel. It may sound negative, but I want to be clear that I do think Silksong is an amazing game for the same reasons that Hollow Knight is.
I played Hollow Knight a couple of years ago, when it already had its status as a legendary indie game, and after all of its DLC content was released. This means my experience with Hollow Knight was an experience of a fully polished and updated game. Silksong was just released and has no DLC content. Maybe my opinion of Silksong is skewed because it was such a highly anticipated game and I went into it with lots of expectations. Mostly, these expectations were met, some were exceeded, and others were not. Overall, I just didn't enjoy Silksong as much as I did Hollow Knight.
I loved Act I, because I was dropped into a whole new world and had so much to anticipate. each new area and ability was fresh and exciting, and I couldn't wait to uncover more. I didn't have a problem with the difficulty, though I had heard how others were struggling. The boss fight at the end of Act I was difficult but doable, but Act II was where I started to understand the difficulty complaints.
Pretty much any enemy, as well as each of their individual attacks deals two masks of damage in Act II. It made exploration difficult and annoying. Every boss became a hassle, rather than a fun combat challenge. I'm not fully against high-difficulty games, but I hated the high density of this high difficulty. Every enemy is annoying. Every area is annoying. Every boss is annoying. It is fine for a game to be hard, but it is also fine for me to be annoyed by this.
Like I said, I love these games for the exploration, the rich and interesting world, and the comfortable mechanics of exploring that world. But the exploration was also worse in Silksong than in Hollow Knight. Everything is hidden behind a secret wall and I felt a lot more lost when exploring. I couldn't figure out how to get into the "Cauldron" area of The Citadel because the part of my map that I needed to explore showed that I had already explored it. This same issue happened multiple times, which I don't recall happening at all in Hollow Knight.
I completed Act II without even getting the double jump and having left at least 5 areas unexplored (because I didn't even know they were there). I was shocked when I completed the game because I thought there was more to do. It turned out that there was more optional content and a third act, which I wouldn't have known if I hadn't looked it up. I wanted to get to Act III because I wanted to explore more and was unsatisfied by the abrupt ending. It took me 20 hours to beat Act II initially. Now, I am at 35 hours without even having entered Act III. I'm not going to keep playing because I'm just not enjoying exploring. And by "exploring", I mean following a guide.
Again, Silksong is a great game and these are all problems that affected my personal enjoyment. It reminds me of Jedi: Survivor as the sequel to Jedi: Fallen Order. I think the sequel is technically better, but I didn't enjoy it as much. this is why neither Silksong nor Jedi: Survivor is in my "When The Sequel Is Better" list.
But Ori and the Will of the Wisps is in that list because it expands on the world and introduces new mechanics while still being a delight to play.
