Seems like a 3D Simon's Quest only with only one true town rather than many.
The wings don't bother me. VOLATICUS! >_> <_<
The music everyone thinks is Beginning... actually sounds more like The DraculaX Chronicles's "Red Dawn" at times. Then again, I wasn't paying too much attention.
Although there are some massive large enemies here, it's difficult to spot "Castlevania" in there. There aren't as many ghosts, spectres, MedusaHeads, zombies, hunchbacks (fleamen). What I do see are large armors and the like, which remind me of the later games (Metroidvania ones) with the large marionette-style sprites.
That is one cool-looking female vampire! The little is creepy but the adult one is kinda sultry.
