Very meh, finished it sometime last year, very mediocre visual novel, with obscure mechanics, you have to click on random dialogues and options in idiotic orders to progress the story, and the story was so straightforward and the mystery so non-mysterious I can't fathom why players 20-30 years ago didn't just reread a Sherlock Holmes novel.
And don't get me wrong I LOVE anime/manga/VN-styled mystery/detective adventure games.
