The story has lots of potential. It started with adrenaline pumping action in chapter 1 and it truly was a great reading experience. I think the choice of 1st POV suits the story well since it's the experience of one person. However, I also think that there is too much introspection (chap2) that some elements already become repetitive. It's also become slowpaced since he had not met anyone yet and still alone for two chapters. Maybe I'm just impatient or I have become one since Chapter1 was quite full of action so the expectation was there. In chapter3 he already met another character and some questions were answered, but only after paragraphs of introspection again. Just a concerned reminder from one author to the next, be careful not to go to the purple prose territory. Also try to eliminate redundancy. All the best author! Keep on writing!
