The whole game is undressing and then dissecting a dead woman. Just a heads-up, it IS actually very graphic.
The philosohpy behind it - honestly, I didn't understand. The game was highly uncomfortable. The author makes a point TWICE to express how hairly legs are bad (one time this actually somehow is used to deduct how she died? But also none pubic hair are depicted and no comment on that difference. Didn't get that COMPLETELY), also there's a hint of fatphobia towards the end. Also it is never explained why is the player undressing her. If we play as a policeman or someone similar - still no explanation why do we NEED to undress her. It just happens as if it's obvious.
In my opinion, this has none of the girly vibes - and also not much respect for women. Maybe I'm wrong, but that's the impression I had.
