The only thing that kinda sucks about this game thus far is the music; there's a few catchy jingles here n there, but for the most part, it's just not memorable at all. There's some sections where there is complete silence, and that drives me crazy! They really missed the mark on the soundtrack, again. That's just sad.
Otherwise I'm really having fun with it so far. No framerate issues have been bothering me, and I'm enjoying the combat (i can see that many people have been exaggerating about the 10-hit to kill skeletons, they're really not that bad, lol). I'm playing with the 3D on and despite what everyone says it doesn't bother my eyes or the gameplay at all. I love the graphics, there's a lot of creepy touches in the stage layout, the subtle nuances are there, and it all blends in with the gothic atmosphere. Only gripes are the [short] QTE's, but they only take a few seconds so it's not as bad as it was in LoS. The boss fights are mildly challenging unfortunately, and the game does tend to "hold your hand" through a lot of the portions. And, dare I say it, I kinda wish this graphical style would continue in future 3DS CV games. If IGA ever comes back to make another game, I think he could learn a lot from this game and how it could improve his next metroidvania(s). As much as I love sprites (I would love a sprite-based game with 3D-parallax backgrounds), there's just so much more that can be done with this style of 2.5D, and I hope IGA considers it IF he chooses to return (although that choice may not be up to him anymore).
Overall, I'm enjoying it thus far ^_^
