Not my first Castlevania, but my favorite.....
It's one of the best DS games out to date.
The music to the game is creepy. Yet it fits the scene. Where better to hear music that will scare the crap out of you then at a place that will scare the crap out of you? The gameplay is like most castlevania games. The movement is basically sidescroller. The weapons are lots of fun in this game. To upgrade your weapons you have to offer souls that you had to get from the enemies. The souls have 3 rarities, 1-star, 2-star, and 3-star. 3-star being the rarist.
The graphics to this game are good, but not anything to brag about. They're basic 2d styled graphics. Better than what the GBA's graphics are, but they're not AWSOME.
Definately one of the best DS games out to date. Shouldn't take too long to beat the game, but you'll have fun playing. It has good replay value also. Mostly because you have to give up souls that you can only get 1 of to get the best weapons. And if you don't care about that, there is always Julius mode which is "Uber" hard.
