Nasu's best writing without a doubt and speaking in terms of Visual Novel; Music, scenery, transition,... This was also the best I've ever played. It's just taking Tsukihime and throwing it into Nasu's current writing, it's perfect. It's a huge improvement over the original. I literally wrote a 64 page text to talk about her. The text is in Portuguese, my native language, but if you're curious a translator can solve it, it's a very technical text.
