there are three Castlevania games for the DS and everyone id diferent
The posibility of mix attacks with diferent buttons basi X and Y, is a new experience on Castlevania on the DS serie, the glyphs that you will got from the monsters make that you pursuit them, and is simply and fresh.
I only play the first hour but I can tell "this game is excellent I enjoy the others Castlevania and Beat it on every mode I will pass this for know all the secrets soon".
on few words this is other Castlevania, diferent power and diferent story from the others if you dont like Castlevania is same of always.
You try to kill Dracula and his empire of monsters, with secrets endings and powers; and when you beat it you will have new modes Vs boses and with others characters.
For that reason if you dont like the saga, all that is boring but for the fans like me is exciting.
Enjoy it and
Bendiciones que Dios este en sus corazones siempre
