Remake version of the second eXceed game. I haven't played the first one, but I'm guessing it's similar. This is a polarity-based shmup -- switch between light and darkness attacks, which have different effectiveness depending on your enemy's element. This makes sense given the fact that the protagonist is half-human, half-vampire. While this element is similar to Ikaruga, I've heard the gameplay described as more fast-paced in comparison. Also the game has some sort of dynamic difficulty system to adapt to how well you're playing, though I don't fully know how it works. The story is a continuation of the tragic tale from its prequel. The music of this game is more metal-heavy in comparison to its prequel. Also, some but not all of the tracks were changed from the original version of this game. I think both sets of tracks are great and would love to see both on GOG. Oh, also, the soundtracks have been sold separately before, so it'd be nice to see them on GOG too.
