thinky-thoughts!
Maybe it’s just because I grew up in the rural countryside and not in a subdivision, but knowing the exact number of houses, and thinking of them as their house numbers feels subtly creepy and imposing to me. Like in A Wrinkle in Time, when they’re on Camazotz and everything matches? That may just be me, but it really sets the tone perfectly for a modern horror.
I feel like a broken record, but I have to like, 32nd the admiration of the sibling relationship. It’s really well done.
Minor errors/nitpicks
Am I remarking out loud about my own hair to myself? That seems a little odd to me. Maybe “You notice how its [color] settles nicely against your [skin].”?
“A walk-in-closet?” Ben laughs, “This place did look that fancy from the outside.”
He probably means didn’t look that fancy, given the description of the exterior. 
“Your surprise lets you lose a bit of your composure, and eye contact along with it.” I think makes would work better here than lets. Lets makes it sound like you were trying to lose composure and you couldn’t until you got surprised, if that makes sense?
I agree that something is wonky with talking to Alex. I end up getting “You only notice now that you never offered him your first name, despite his doing so” even when I do give my first name in my intro.
On the stats, you said you’re planning to edit them a little. The one I think is a little off to me is Direct vs. Polite. You can be direct and still polite. Maybe direct and subtle? Or blunt and polite?
I’m really taken with Alex, as I’ve said in multiple places already. Nosy code spoiler: I am reallly interested in the other stat related to him in code. Respect? Hmmm… I replayed and like Rae and Elli both too, but I’m definitely romancing Alex on the first playthrough.
I’m really excited about this one, and I’m not generally a huge horror fan? I guess it’s just that film horror often veers into gore and that is not my bag.
