It sounds fun, from the little gameplay I've seen (I try to keep dark on most things I plan to engage with even going years without being spoiled) I think It looks like a my cup of tea game lol I also had seen/heard it is a bit more difficult which always perks my interest. I like challenging games because I find it more engaging.
But I also got a vibe like I did from ico from it which may sound weird but that kind of exploration and puzzle element..

Thank you for the write up, hopefully you'll get to experience more of the art when you get back to it, I think it's got a really nice artstyle too, what drew me to it too ^^
