As a fun throwback to Castlevania, I'd love an optional boss fight against Dracula; possibly as a boss in the randomized bonus dungeon, or just tucked in a corner of the castle that only unlocks after you beat the game. It would be a great way to play off the nostalgia of Castlevania (and totally legit, since Drac is public domain), and probably be a fun fight to design and create, putting a Timespinner spin on some of his classic moves and making up some more of your own.
I always enjoy beating up the Count; I'd love to have another chance to do so in this game.
