Ok so watch the first ep and they definitely managed to make it interesting. It's very similar to the game while being very different story wise. Animation is ok and the faux-hatched style is very apparent which is a nice touch but I have a problem with the charadesign : the eyes are too big, especially Isara's. As far as music goes it's mostly music from the game, the opening theme is good but the ending theme is so-so with omake-like characters... from what they've shown in the opening most of the sub-cast will appear in the anime. This episode covered only part of the prologue of the game (untill they unveil the Edleweiss).
For those of you who want to take a peek at the anime (raw) without downloading you can do it here :
