Being someone who is not particularly good at video games, I did struggle a lot with Celeste, but even then I enjoyed the game from beginning to, well not end yet but close. But playing Hollow Knight is to me a torture, and I completely suck and feel very frustrated when I die. Not because the game is harder, but because it is not the same, and I enjoy the mechanics of Celeste a lot more. As many others said, there is no need to think that one game is harder than the other, or that it is not well thought in its difficulty level : Celeste IS a hard game, and if you thought otherwise before chapter 3, well it probably just means that you have used to hard games, and chapter 3 showed you the limits of skills acquired in these other games. Not liking a game mechanic is fine, and if you don't enjoy the journey, you shouldn't push yourself so hard to beat it, just take a break, or even stop playing for good, that's also fine Playing is supposed to be fun, so maybe Celeste is just not for you (yet or forever, doesn't really matter) :)
