I am a bit nosy...
Giving advice even when not asked. A bit of a bad habit.
Don't know if you made the corrections already. But here goes.
You need to watch the spacing with the sides. On the mobile version of your novel there is no space left between your words and the end of the webpage.

Took a screenshot of another novel so you can see what I meant.



I did find several typos here and there. Your sentence structure plus grammar does need a bit more work but nothing that will kill the reader. I do suggest working on sentence structure plus grammar to better pass your throughts to the reader.
The info you give can be excesive by a tiny bit but nothing that is a deal breaker. I do think most of your problems will be fixed by writing sentences a bit more eloquently. That way your ideas will be clearer to the reader.
Having said that your chapter 1 may be a bit long but not a deal breaker (that is mostly personal preference).


Instead of writing your authors note there use this section:

Finally I was expecting way more profanities and gore.

I think I only read 1 profanity but no gore. You did mention blood but the descriptions weren't goreish tbh. Maybe I missed something?
