Very promising start so far.
I always liked these kind of horror movies, so the plot will most likely be to my taste (allthough not really shown atm as it is a rather early version).
The characters we got to meet (outside of the prolouge) are both beautiful and lovely. It is important for me to have quite unique personalities in LIs when it comes to non-harem games, and from what I gathered so far you'll accomplish that nicely. The main character is beautiful and I allready am anxious about losing her to a dire fate.
I'm excited to see how you'll present the late 80. vibe in regards to public behavior and general belief, especially when it comes to same-sex relationships and the repercussions of it. Most horror movies from that time period had still a fixated hetero-only mindset, maybe with an odd shoe-in of the stereotypical rebel lesbian.
Since your male characters so far are rather disgusting, I really hope we don't have to endure larger portions of "voyeur" scenes. Maybe throw in one or two more likable examples for good measure?
All in all I am very excited to see where this will go. I won't leave a review yet because I don't think there's enough to do it justice. Keep up the awesome work.
Oh and best girl
