Hey! This is super great. I understand what is being said about rough edges, but I think there just needs to be some smoothing. In general I love the style, and I lovet the scope and feel of what you've created. I really feel like a PI!
In general I ran into two big issues. One was the lack of controls being explained. I had to restart my save file a few times because I wasn't sure how to control the gosh darn thing, and wound up shredding documents I wasn't supposed to.
Another thing is in the photo minigame, this is DOUBLY true. I don't kno how to zoom still, after futzing with it for a while. Eventually, the image of the building dissapeared and I was left with a white screen and camera until the timer went out. This is definitely a bug and should be addressed. In general, I think having the controls on the screen in some way will help-- the buttons are always changing
