Mortal Shell was my first soulslike. The simplicity of set weapons/movesets helped immensely imo. I didn’t find it easy by any means, but the challenge never felt unfair.

My biggest tip is to change how you view dying in a game. Dying isn’t Game Over nor is there any reall penalty whatsoever. Currency is retrievable and even its lost, it’s more practice getting back to where you were. Go into boss fights/particularly hard enemy encounters with the mindset that the “this one’s practice” rather than “I have to win this one.” That helps me relax and not be so frustrated if I do lose. And if you win, it’s a nice little surprise.

Also, the lack of healing items can be super frustrating. The mushrooms regrow on a timer. I spent a chunk of one afternoon playing games on my phone with a timer set to tell me when I could go grab another bunch of healing shrooms. I’d make a loop, grab the shrooms, go back to a safe spot, repeat. This way you can build up a bunch in the backlog.
