Of course, it's an idea that never really wants to go away. I do kinda dig the thought of everything being in reverse. It's an interesting idea for building a whole second world, and it's something Castlevania hasn't really done yet (that series being stuck going back again and again to the SotN well).
Stupid Symphony of the Night. You're a great game, but you shouldn't be the series.
 
    

When evil spreads across the land, and darkness rises and the monsters roam. When the creatures of the night make beautiful music, and the things that go bump in the night go bump with greater enthusiasm. When the world is in peril and is in need of a hero...

These guys are, sadly, the best the world can hope for. These are the adventures of the heroes of CVRPG. They mean well, they try hard, and occasionally they do the impossible...

They actually do something heroic.
