That's because some people are trying to play it as an RPG, not for what it actually is: a rape sim.
It's a pretty fucked up game which requires a certain mindset to play. You basically either have to be into rape fantasies or have a victimization fetish. If you come at it from any other angle, you're going to have a very, very bad time.
The silhouettes are a manifestation of her trauma and you are experiencing it through her eyes. Someone who is undergoing sexual assault isn't going to stop to admire the features of their attacker.
Game is intentionally skewed to make you lose and the quests are intentionally made vague. It's to create a feeling of helplessness for the reasons mentioned above.
The ending sucks, because this isn't a game you play to beat.
None of that is the reason I quit playing it. The game literally has nowhere to go. Even if it isn't "a game you play to beat", it still should have movement/flow.
You walk around..can't even run or walk faster. You go on a quest to find random useless items. The quest rewards nothing that matters. You get raped by random people and/or monsters, and yet you still get up and continue doing pointless quests. There's no story. There's nothing really in the game other than moving around to get fucked over and over. "Pregnancy" is in the title, but that never happened. The game kept crashing and/or freezing. The controls, from what I remember, were horrible. The camera view was garbage. How in the hell should I be able to move around and see where I am going if my camera view is of the ground the entire time? I would have to redownload it and run through again just to remember everything that deterred me, but it isn't worth the effort. I don't call it garbage for anything you mentioned. I call it garbage for bugs, controls, camera angle, layout, gameplay system, and other technical issues.
I play rape games often. It's not really a fetish to me, but certain aspects can be interesting enough to keep my mind in the game. The concept of rape isn't what ran me off.
