Nine sols! It's only on Steam at the moment though, if you're on console.
If you're a fan of sekiro's combat mechanic, this game is a must play for sure. Some people compare it to hollow knight, but I'm not sure I see the resemblance (coming from someone who cleared P5).
My only complaint with this game is that it's too short (~15 hours if you're moderately skilled).
EDIT: alternatively, you might wanna try Celeste. It's a challenging platformer that offers a judgement-free assist mode if you're struggling. I think it's the best handling of "easy mode" I've seen in any video game.
Both games are incredibly fair, and not once did I think "this is bullshit". Difficult enough to test your skills but not rage inducing for sure. Loading screens are also really fast (compared to the extremely frustrating fromsoftware loading screens), so honestly dying isn't any issue.
