I really enjoyed this game. Good music, nice graphics and an interesting game mechanic. I like how you are able to make deductions. When talking to people there only seem to be a few options which start a conversation, the other options are a standard line for each character. I think it would be better if the characters had lines for every note, even if they amount to nothing in the end. For example, it would make sense for a detective to ask where the people where when the crime happened, so the time note could trigger 'where were you that night?' for every character. This way some characters could have aliases. It would also make sense if notes could be reused with other notes to make other deductions, although this could make things complicated.
Overall it is a great game and I look forward to more games like this in the future.
