I didn't think there was one floating around out there. Now I've got the urge to play this game for the first time in a long time, maybe I'll toss it in the ol' Nintendo tonight and give it a whirl since it's been so long. I remember it being a lot like Castlevania mixed with another similar NES game but I can't remember what, but I do remember the grappling hook which set it apart from many other games and jumping on top of enemies early on.
