I got this game few days ago, and I absolutely love it. I never have been into fighting games, and complicated combos, but this Castlevania just makes me want to play it more and more.
The trick is, those complicated combos are not around in this one. It's all about finding a right spot to attack, and then strike strong. I found it very Castlevania-like, altough it's a fighting game. Castle mode is my favorite so far, great fan service. I hope this would sell 30 000 copies in Europe and Austarlia, so it would reach 100k worldwide sales, but I have the feeling, that this non-advertised title will just get lost from players.
