Two things:
– This is not the kind of background music which allows you to read and think about long paragraphs. Ominous music is fine, but this too intense even when there's not too much going on in the dialogue. The key to good horror is knowing how to use *silence*. Although I liked that you play sound effects at certain times; that's a good idea.
– This is not the kind of background picture which allows you to read long white paragraphs. It's colourful and changing which makes reading harder. In contrast, the dialogue lines come in a black box which is way more convenient. I'm not sure if the backgrounds could be considered "disturbing visuals" – there are too many filters and it's too blurry to fully discern what they represent, although sometimes you can guess.
For the above reasons, I couldn't really get into the story. I read it three times just to confirm what you say results in the same response (which is a no-no – why even have the choice, then?). There's also an unwritten rule in literature that you shouldn't use digits for common numbers ("20 something years", "80 bucks") unless it's too complex or a scientific calculation etc.
The story itself just didn't ‘grip me’ enough. There's not a lot of going on except for a barrage of (repeated) swear words which can't magically make your story more intense. Unless I missed it, there's no truly thrilling moment or a plot twist and boils down to "a woman murderer is calmly arrested for desecrating graves". But perhaps there's more and I just missed it, partly because of the distracting music and backgrounds.
