Leaving my in depth feedback comment here while dropping a short comment for those that check out the game page on there :)
Overall, this VN is very well done and has a nice polish to it.
The art fits the dark and disturbing tone of the story and the voices had nice effects later on.
The text messages inside the phone were cool. I didn't notice that you could scroll back up at first, but that's an awesome feature. Maybe you could have used that scrolling animation on click so that it als kind of scrolls up whenever you get a new message!
One time, the thunder coincided with a voice line, sadly drowning out what was said. Not sure if that was on purpose or if the sounds are just a tad too loud.
At one point (sadly I didn't get to screenshot), the narrator switched from first to third person. I didn't pay a lot attention to this, so I couldn't tell if it happened more often and was possibly done on purpose, but if it's a slip up, I wanted to let you know.
I read this with friends and we were constantly wondering what's going on. There are tiny hints that some of us caught that I may have missed otherwise, so I think a second read-through may be necessary to piece everything together (assuming all the answers may be in there *somewhere*), so good job on making it nice and mysterious.
Very unsettling VN that fits nicely into Spooktober. Well done.
