Doesn't look that bad, really. The framerate is still bad (if you can't see, you're fucking blind, seriously, even on the youtube videos being capped at 30FPS you can see some slowdowns), but the platforming seems pretty good. I'm not sure about the enemies getting only few hits to die... it seems to me that the game is being played on easy, and on higher difficults, the enemies only die with more hits, like most of the modern action games out there. =/
Still will get... it's Castlevania after all. But I dunno if I'll be satisfied with it...
