Not sure how to review the game in further detail without giving away too many spoilers: Even though once you figure them out, some of the hints gave me a headache because I was concentrating on completely unrelated things rather than the actual clue. Your wife has incredible talent! I completely agree that the artflow is unique because of the sketchy technique. While admiring the limited but lovely details in the pictures, I even forgot that I was trying to solve a crime. Even though I've already gone through it, I feel like I could keep playing. It's been a bit since I discovered something "fresh" in a genre I assumed to be too familiar with.
I was initially irritated that I was forced to ask the same questions to everyone and that the clues did not lead to the discovery of new questions, but after a while I understood and, on top of that, I began to enjoy it. I'm almost positive you had music, but I'm not sure. I guess I should start playing again. :)
