Castlevania Legends for Game Boy is a really great Castlevania game, compared to the first Castlevania Adventures for the same platform the movement is smoother, it feels like the character is a bit faster, the whip responds better and most importantly of all: THE HEARTS DO NOT GIVE YOU HEALTH! Like we have learned in previous Castlevania games, the hearts you collect are used for your special ability. In Castlevania legends you receive special abilities after each stage, instead of collecting them through candles, and they’re called soul weapons. You use them like normally in Castlevania games, by pressing up and attack. But there are also a few hidden weapons, like the holy water, throwing dagger etc, hidden in certain candles in a secret area of the maps of each stage (not really secret, mainly just a detour from the standard route).
Another different thing about Castlevania Legends is that you play as a girl, called Sonia.
Through the Super Game Boy for the Super NES they have improved some graphical aspects of the regular Game Boy games, such as giving Castlevania Legends this really neat interface with pillars and stone around the screen instead of the normal boring “Game-Boy-Look-a-Like” screen.
Also the stages have different colors, which makes it feel like you’re really advancing through the game. Here’s some of the stage colors, and in the bottom right corner is the standard sepia/brown that the Game Boy games had as a standard through the SNES.
Some downsides of the game… the bats are annoying as usual and they come in groups and respawn on the screen when you are trying to advance upwards, creepy flying 
black shades pop from nowhere and have a really annoying pattern which makes it really frustrating to try to hit them, stupid big ass 
knights that charge you and take way to many hits to kill and hurt you way too much, (SPOILER ALERT!) Alucard is actually one of the bosses (even though he’s a friend to the character, Sonia, he needs her to prove her strength) but he is way too easy to beat =(, Alucard is supposed to be kick-ass!! There are also some special candles that have a different color than regular candles, DO NOT HIT THESE, since they will make you fall into a pit of bad guys which won’t let you out until you are almost drained of health.. stupid…
Apart from this Castlevania Legends was a really great game, but Aria of Sorrow for Game Boy Advance is still my favorite ^_^
Here’s a video I put together of the music, the gameplay, the stages, the bosses and so on.. enjoy! =D
