I gave it a try last night. I reached the fourth stage and tried my luck at beating Frankenstein ('s monster), three times or so. He's always at ridiculously low amounts of health (like two or three bars) when I get killed by a fireball (or whatever it is that midget throws at you). Those things hurt. The strategy I'm going with is to try and disable the crazy midget whenever he's coming at me, because when disabled you can just walk straight through him. Also, I'm staying around the middle where I got lots of room to avoid the fireballs, and am able to reach Frankenstein with the whip.
However, I just thought to myself that I wouldn't be able to finish it then, at least not quickly enough. I'll probably give it another go this weekend, with the dedication to reach Dracula.
