I love this game, especially the Nice BGM, kawaii girls, horrible sound, and supernatural things. But what is the "ending"? Is ending defined as goto game's home page, or just show the logo of "The Snow is Red"? The final "ending" is only Noir give MC a big white snow droplet or still have any other one(I wish Claire could be my girlfriend)?
More interesting things, are you REALLY experienced a girl that causing Laptop BSOD or other type of GUI crash? I have seen my preview-girl friend causing Win10 laptop & iPad crash(Win10 BSOD, iPad BlackScreen with iOS continue running) multiple times! So you may would like to PM me at my GitHub (UEFI-code) for more horrible & Hentai Ideas!
Additionally, I think the Bathroom similar as the Japanese "Ju-on"(I like this movie much), Kayako & Toshio action that make blood water and mirror ghost shape. Claire might also have ability like Sadako in "Ringu" that can control TV or electronic's current? I'm interested in your novel, maybe available to download?
By the way, maybe the game application logo on the macOS can be more cute, and changing at runtime, as some type of metagame.
