An excellent game. Castlevania had my interest from start, to finish. The card system was a good addition, but some of the combinations are useless. I had no problem with the darkness of the game, as long as I was playing under a light, or in direct sunlight. Besides, Castlevania is "suppose" to be a dark game, not a cheerfully bright game, filled with pastel colors. Can be a bit hard in areas, but not to the point of becoming frustrating. A must have for the Game Boy Advance...
