Hello! I was one of the streamers who took part in Feedback Quest, and I'm here to leave some comments I had while playing.
Originally, I had the plan to judge this game primarily on its logic for who the murderer is. However, since the game is not finished I'm unable to do this (or at least I couldn't on the path I took). I do hope that if you submit this to a future Feedback Quest that there will be at least one complete path to allow for judgement on that.
I felt the intro text went very fast. I would like to see it slowed down so it can be read in full (especially if someone is streaming it as I was). I also felt that some word choices were a bit confusing. However, this could be a result of translating. I also felt it was awkward when Anastasia was being called "Princess Anastasia Konstantina" in narration without any shortening, to the point where on my stream I started making a joke of saying her name very fast so I could move on. It makes sense when speaking to her, but not in narration.
While I like the art style and generally liked the artwork, I did feel like most of the cast were drawn in ways that didn't match with how they should have looked. Joseph's artwork made him look like a child despite him being only a couple years younger than most of the other patients. Most of this alternate cast looked like teenagers to me rather than adults in their mid to late 20s. When I eventually read that Emilia was supposed to be from India, it made no sense to me because of how light her skin is. Meanwhile, in all of this you have Dr. Adenauer who is supposed to be in his 50s but looks like he's over 70. Also, Anastasia has a huuuuuuuuuuuge forehead. I couldn't stop staring at it. D:
