Woot, completed it! (God, I hope I accused the right one - can you accuse the wrong suspect?)
This game is super big. There were some bugs (like sometimes I could talk to people while invisible and some sparkles weren't on the correct object and didn't go away), but that's too be expected considering the scope of this game. Some of the dialogue got scrawned in my ending, which was a shame.
I think I completed most (all?) of the subplots, but on that note - I would have really loved if the Clues actually had some clues. Even just hovering over that subplot or clicking on it and have a note appear with everything related to it, would have been very nice.
I liked the news ending, but some of the news was repetitive. The newscaster announced at least twice that Sachiko was the new countess.
