You are really good in creating a specific mood & athmosphere.
I really liked the themes of warping, restarting reality, but of course it felt also confusing, which seemed intended.
I personally find it exhausting to follow a protagonist that is completely desperate & cynical. It does not help that I really don't learn WHY the protagonist is desperate.
I appreciated the unbroken will through struggle, but I could not find any reason for the protagonist to struggle..
I pitty him, which means you got me emotionally involved - a good thing. I got the feeling the protagonist is a little too fixated. He is NOT searching value in himself or a value in the world. He seems to be driven by one goal & seems to despise everything else. He also doesn't seem to change. So I as a reader did not learn anything valuable from him.
Overall: I as a reader miss a moral/lesson & meaningful relationships. But I like your general writing-style, ability to create mood & also the worldbuilding, even if it felt a bit chaotic.
