My comment contains SPOILERS, if you haven't played the demo yet scroll back up.
I was debating whether I should leave a comment or not as I'm not even the target demographic, but... eh..
First off, the title of this game and the double theme (society -> genetic matchmaking/ Eden's attempt to mutilate forge MC into the perfect partner) are a perfect fit. The menu music? It's called Bluebeard. Also fitting.
There is a really good cohesiveness here despite having many cooks working on it. Be it sprites, backgrounds and even the choice of font. There is also nice contrast going on with how clean and empty (less being more) the backgrounds, UI, sprites and CGs are, compared to the game's merciless and gory nature.
I played through the end. *Extreme body mutilation is not my cup of tea. So I cannot say that I liked that, but the theme is good and it was an interesting read.
Really good and memorable music. "Brownout" feels sentimental, like days blending into the other. Suits the MC and her "best" friend hanging out and being poor souls trying their best.
* This is not a criticism of the content of the game. Maybe a view point from someone who isn't into mutilation, or at least that much? Sometimes you need to play something despite content warnings to see if it's something you enjoy. I do like dark content. Composition and intensity of that said content comes in flavors. Sometimes you ain't into it.
