I also was not a fan of Hollow Knight. My biggest problem was the constant backtracking and not knowing where to go to progress the story.
If you want a great platformer in a similar vein to Hollow Knight that has a beautiful art style and punchy gameplay, check out Ori and the Blind Forest and Ori and the Will of the Wisps.
Oh! I really enjoyed Hollow Knight. I found that although i sucked at it going in and struggled so much with even the first boss, once i got my head around it it was one of the most rewarding games i have ever played. Trying over and over to beat a tough boss and eventually winning felt great.
I got Silksong recently and just beat act 1. Incidentally the movement controls in Silksong are VASTLY superior to Hollow Knight. You might even enjoy it.
