it was awesome

Not to be overreacting but you're book is totally awesome. You're innate writing skill is what the world should witness. Try joining NovelStar's writing competition because why not?

Hmm... this is super good (I guess I'm dead), I wonder if it'll go any further...

I like this, except for how itswitches to past tense in the middle of paragraph 6. It detracts from the immediacy of the story, and there doesn't seem to be a reason.

If it were entirely present, it would be a spooky, haunting story, and if all past, it would feel like the "you" was a ghost. Mixed, it feels odd.

Your descriptions feel very realistic! Will there be another chapter, or does "you" just die?
