While Necromancer's Abyss was one of the most complete stages, I've got to say it wasn't one of my favorites. Truly, my favorite stages were the ones inside the castle (chapters VI, VII, and VIII) and the mountain fortress (all of chapter IV). They were also the most Castlevania like stages of the game. The only problem is that the skeleton warriors are way too strong. I mean, traditionally the skeleton enemies are weak in castlevania games.
