Did you get to play the original (Monochrome)? I have roughly 10 connected visual novels as well as an ARG that ties into them spread around the internet in various clues, creepy websites, and a youtube page tie-ins. It's all pretty messed up (in a good ole' cosmic horror sorta way).
Yes, I intentionally did that with the music. Somehow it psychologically effects the reader/player when their mind registers that something about the melody is 'off' from what it previously (or normally) should be, creating unease. Doki Doki Literature Club did a hell of a job with that, too. ^_^
I hope the Weather Channel was informative, too! xD
