The game needs to be run in full-screen mode for me in order for it to display the UI properly (I had the same issue as Franzinyte where starting the game causes it to be zoomed into the top-left corner, but I found the full screen button by chance), so getting it started was a bit difficult. The visuals look fantastic, and I love the watercolor effect. One thing I didn't like as much was how the interface would swap between right and left with the character's image and the text/buttons. I would prefer that interface to stay consistent
Hitting space seems to "restart" the typing animation for that screen, which I'm not sure was intentional? I also had some trouble figuring out how to move to the next dialogue section until I tried clicking the "continue..." text. I think the continue "button" might actually be taking up the entire text box, since I noticed that the border and background on the text disappears once the end of that line of dialogue is reached. The dialogue runs a little slowly, so I would have liked an option to speed it up or remove the typing effect.
There were several grammar and spelling errors, and some of the vocabulary choices felt odd (some felt too out-of-place for the time period you were going for). However, each character's voice was consistent and distinct enough that I could tell them apart by text alone, and that was really good! The story was a little difficult to get into at first though, and I would have liked more context or even a debrief the way that I'd expect an investigator to get before arriving on-scene.
