The art is gorgeous, but the literal translation is painful to read.
Also the first act is a horrible drag, it's just one info dump after another about the most boring parts of the lore that could be explained later and more organically. It doesn't help, of course, that it's all delivered in what feels like a poor machine translation.
Add to that the fact this VN essentially has two opening acts, due to starting with a flashback sequence, and you get a very-very boring beginning for a story.
I hope it picks up later.
EDIT: It does get better, writing-wise, and the translation gets much-much better. Hopefully they can get around to reworking these earlier amateurish chapters sooner rather than later.
