Great graphics and quite challenging.
The game-play is going to be very familiar to Castlevania fans, with the addition of using glyphs instead of a physical weapon. There are a-lot of familiar enemies and some truly wonderful bosses, including Dracula (ofcoarse).
My big complaint is that the side missions you get from the villagers really feel like chores. Whether it be finding a mouse, taking picture, or finding ink for a pen, you really have to wonder if the missions could be any sillier. The rewards for the side missions are pretty weak also. Perhaps if every side mission rewarded the player with some type of weapon or armor, it would'nt seem so tedious.
All in all, Caslevania and Metroid fans will be absolutely delighted with this game.
