Yay! a Van Helsing ripoff! XD
Nah, i'm kidding. I liked every part of this. The art and animation were both smooth and the voice acting wasn't too bad either. I am pulled into the story i.e. you got my full attention and i want to see more. Also, the vampire joke at the end of the credits was pretty funny.
My only problem I have with this is that it did feel a little bit short, but i guess that's why you are telling us this story in episodes.
