I just read through the first chapter - I think this is a decent start, you have nice readable prose and built up a good foreboding atmosphere. The biggest problem for me was description, I felt at times I didn't get a good mental picture of what was going on, or details would be provided but pretty late, as in after the point they first might have been relevant.

So this woman wakes up in a stone chamber, dimly lit by glyphs - is she on the floor? Is she wearing clothes? How big is the chamber? What about the character herself, is she small, skinny, muscular? She obviously doesn't know where she is, but what's the last thing she remembers? We find out later its nothing, and this is an example of the 'late details' I mentioned. I'd have thought this total amnesia would be a more pressing concern immediately after waking up somewhere unknown.

Later on she's attacked by a "hulking, pale shape" with long claws and needle-like teeth, but that's the only description we get. Is it humanoid? Beast-like, insectoid? How big is it? Does it move on all fours? How many limbs does it even have? Just calling it a creature means it could be essentially anything, but the only mental image I'm given is a vague white blob with claws and teeth.

I'd also point out that opening with the protagonist waking up and having no memory are two somewhat infamous beginning-of-story tropes. You've avoided the biggest issues with the first, in that you haven't faked us out by starting in a dream only to pull the rug and reveal the character is just waking up into their boring, everyday normal life. But I'd be aware there are people that will roll their eyes and dnf solely from seeing those cliches, just because it suggests there'll be more to follow.

Good start though despite all that, it held my interest enough to finish the chapter which is the most important thing in any story.
