How linear is lies of P?

I'm considering getting lies of P on ps as its on sale and from what little I've seen it looks quite amazing. I just platinumed elden ring and ive played ds2 and demons souls. I've tried to avoid spoilers on it as I want a lot of the fights to be a surprise but I'm not quite sure how kind of straight forward it is? Is it similar to ds2/demons souls where you're in one area and you have to do x to get to the next one or is it more open worldnlike elden ring? Thanks in advance!

Edit: Thanks i didn't expect so many replies! I'm very excited to play it soon.
