My personal favourite has to be the Hide&Seek ending - the scenario of bodily posession is rare to find in similar yandere-vibe projects. It fills this obscure niche I didn't know I've been interested in exploring more, even in my own writing. This is like a breath of fresh air for my understimulated imagination. I've fallen victim to hyperfocus when working on my manuscripts as well, so I can fully understand where you're coming from, making a separate Director's Cut version XD. Good luck with your other projects!
P.S. the music box is full of bangers, as always <3
