Castlevania Chronicles is a Playstation game that is a very close remake of an older Castlevania game which means this game has nail biting, hair pulling, controller smashing difficulty. So don't play it unless you are one of those really enjoy playing levels over and over and over again. Because it is hard. Extremely hard and only serious (completely insane) gamers need apply. That being said, because it's so hard when you do finish it you'll definitely feel a true sense of accomplishment marred only by the fact that you want to throw this game away now.
By the way, I was playing on Easy and I still found it nail bitingly difficult.
