Maybe this game isn't for me. The presentation and style is fantastic, maybe the strongest I've seen in a VN, but I couldn't get into the writing. I was intrigued by the unexplained elements, but the first narrative "hook"/horror moment fell flat to me. I think because it showed too much of it hand, and didn't leave much room for the imagination That's why the unexplained elements gripped me more than this setpiece.
I hear there's twists, but I stopped at the first number puzzle and didn't feel hooked enough to continue.
That being said there's clearly a lot of work on display, and the mechanics are very strong, so kudos and good luck on the project!
