First, let me say I haven't read all 5 pages of comments, so it's likely that what I'm about to say has already been said.
Everything up to 0:53 is nice. If fact, it's the best part... and I'd hate to say, but it's downhill from there. But I really do like the first 53 seconds. But right at 53, the trumpet kicks in, and it's too loud and doesn't seem like the best sound to be using in a beat like this.
1:15 to 1:36 is good. Hooray for no trumpet. 1:36's vocals are subtle enough so they don't interfere with the remix, so that's okay. But at 1:46 I think everything falls apart. Don't get me wrong, I like rap, I make rap, I've got nothing against rap (except mainstream crap), but the rap here just seems terribly out of place.
I briefly read that no one could understand the lyrics... if they were recorded/mixed properly, there'd be no need to post the lyrics. While the lyrics sound as if they have some potential, it's still very amateurly performed and mixed. No offence... you want sincere criticism, come to me, I'm an ass, but I tell it to you straight.
All in all, be happy you got me to comment about it, most remixes won't motivate me enough to comment. But anyway, I do like most of the instrumental, and Castlevania II is one of my favorite vintage NES games.
