You know I've played a lot of yandere games and I think this is the first one where the yandere in question has immediately triggered a "no no no" reaction in me right from the beginning.
I wasn't entirely sure what to expect with this game when I booted it up but it ended up being genuinely uncomfortable to playthrough (in a good way). Louhi is quite horrifying, I never felt safe with him for a moment and was immediateley trying to say no and get away. There's a real sense of helplessness with just how little your choices matter. I also like how his backstory explains his actions and attitude, but to me at least it never felt like it excused them. Yes his backstory was genuinely quite sad, pitiable even, but every time he started playing up his sadness to garner sympathy I was sat there yelling at the screen "Maybe I'd feel more sorry for you if you weren't constantly bad touching me!" It's quite refreshing to get such an unsettling character all the way through, full props to you for being able to write someone so effectively disturbing. However I am a little confused as to how the MC sees him at times. Him just pushing through our boundaries no matter what we say works to make the situation feel more uncomfortable and violating, but it's a bit weird that even if I've said no at every opportunity the MC still seems to react positively to these actions (especially when she says she feels safe with him in bed, that really rubbed me the wrong way). I don't know if that means Louhi was deliberately manipulating her feelings to make her enjoy what he was doing, but it did make me disconnect with her more than once. However other than that the story was really good. I like the concept of Upirs and how a lot of details linked together as it progressed, plus the art and character designs were really nice to look at.
I was very surprised at finding out this is apparently a demo, it felt like a pretty complete story no matter what ending was reached, so now I'm quite curious to see where this will end up going. But overall I'm glad I gave this a go.
