So, wait, are necro-bumps allowed in Castlevania threads because, you know, Dracula?
Before this gets locked, I'll throw my $0.02 in. I can't imagine anyone disliking this game unless they're looking for something to complain about. It's basically a portable SOTN. Not as atmospheric or beautiful, of course, but it's structured like SOTN and plays exactly like SOTN. I find the soundtrack to be crude, but charming.
The thing I like best about this title, though, is the dual castle design. Instead of an inverted castle or different worlds, you travel through one castle in different dimensions and can also traverse both dimensions at once (A+B). That's pretty damn ambitious design and the game pulls it off.
