The art is stunning, story is interesting, I felt going mad from "to be continued" in the build 2. I'll definitely will keep this vn on my watch list.
A couple pieces of critique though: please, pretty pretty please add a gallery. The artwork is really awesome and it would be super cool being able to see it at will. Another point is the characters, and this is far less objective. Most of them are so mysterious that it makes too hard to understand them and their actions and I end up more confused than intrigued.
At any rate that's just build 2, hope I'll have some answers and (much more) questions in upcoming builds! Keep up the good work :3
