Wow, I hadn't seen that before. Whatever people are saying about the quasi-3D graphics at this point, I won't hear a word against the art style. The backgrounds have continuously impressed me - not only is it Castlevania-ish, but it's even MORE Castlevania-ish than a lot of the Metroidvanias. Super dark, eerie, and atmospheric.
My biggest concern now, since I haven't played it, is how well they'll manage to iron out the framerate and control fluidity. I remember reading that the controls felt clunky. Nothing will depress me more than seeing this extremely promising game get 7/10'd.
At least, Fall's a ways off. They have some time yet.
