Paleblood Hunt intensifies

it’s my first souls game i have completed, first one i played was elden ring

It's actually pretty easy to get working on PC (in 60fps) these days with emulation. Like you get the emulator, and it literally has an option to connect to the bloodborne 60fps rom hack repository within the emulator itself.

Haven't tried it on Steam Deck specifically, but it worked surprisingly well on my laptop when I tested it out several months back.

Don't have the link off hand but it's not hard to find. I could probably find the link if someone really wants it and can't find it themselves.

EDIT: not sure if counts, but I did a good portion of my BB playthrough on my Deck, streaming from my PS5.

Wow how did you make that work?

That depends on the player; It's as hard as you want it to be, (you can over level if you're struggling, or do a challenge run staying under level, no upgrades, etc.) definitely not hard compared to today's soulslike standards. If you are new to the genre it may take some adjustment, but the game is worth it.
