Hello! I have yet to play the game but it looks nice! however I've seen some typos in the main page(also some recomendations) , so I hope I don't come out as rude :p
So first I would recommend you to change things like "You are a detective who has just moved to a new town. You are involved in a serial killer case" to "You are a detective who has just moved to a new town and are involved in a serial killer case" do you get what I mean? Like don't separate every sentence and just try to stick them together
Also I've seen a small typo in th MC introduction, like "She have" instead of "She has". Besides, I would recommend changing some words since in some sentences the choose of words is a bit poor
And something that also may bugs the eye is writing on the same sentence or paragraph both "He is" and "He's", maybe stick to one because it looks a bit off
The rest seems good! The main issue would be the sentences thing but overall it looks nice, so keep going! ^^
