God... I love this game so much.
First and foremost, I am going to talk about the music because I loved it so much. I spent so much time just straight jamming to this game's music; I'm gonna save the damn OST now. I really love it, as it helps give this game a standout identity alongside the U.I.
I love the writing as Sid as a protagonist. She's such a fun character, and I honestly get her headspace so much. She had a horrible home life that causes her to internalize a view on life that is simultaneously naive/stubborn and rooted in deep self-hatred. Her development into a more selfless person is also such a standout part of this game.
It also helps that you can genuinely see what traits of her personality make her and Val such a good couple. While we mostly learn about Val from the perspectives of others, she feels like a fully fleshed-out character with her own life and story bubbling beneath the surface.
Another thing I must bring up is just the masterful amount of foreshadowing and fridge horror in this game. It's so much fun seeing rather innocuous details slowly get uncovered as extremely important.
This is one of those games I think I'll have to sit with and think about for a long while. Good shit!
