So: I adore Marie-Helene and I think all her abilities rule. Letting others gain a little bit of Blood whenever she feeds? Steal an Attack dice of an enemy? A persistent cough as minor harm?
Brilliant. No notes.
The layout and art is incredible. As someone who had to work really hard to come up with something passable under the deadline, I'm extremely impressed with the work done to make it really match with the design of the core book.
My one thing is that, while the Grotesques are conceptually really fun and interesting... mechanically I wish they had more to offer. The one big innovation is the countdown clock which'll add a bunch of fun tension, but otherwise they're just another bag of hit points that players have to whittle down (while the players are probably close to finishing up anyway). I know that Devil Whale Games can write extremely cool abilities... just do one more and I'll be overjoyed.
