Hey, you can’t end it there, I wanted more resolution! >_< Joking aside, I might have missed some of Anna’s development, her dialogue in the last scene surprised me (the dangers of experiencing a story through a stream, I suppose).
The premise is simple, but the execution is great. The story has great pacing (maybe the part before the coming out is slightly too long?), the characters are fleshed out very well, and the backdrop of the manor-museum is really cool. (Why are there wolf structures in the middle of a hallway, though?^^) The writing is really good as well, no problem there. The folklore is more in the background but has enough influence to be felt.
Presentation wise, the sprites look really nice and expressive, the CGs complement the flashbacks perfectly, and the backgrounds fit the place and atmosphere really well. Music wise, there are a few too many silent scenes, but the rest is good. The UI is nice as well.
Overall, this VN is great. I don’t have much else to say.^^ Great job!
