I keep killing Wadolf, though by the time I have barely any of my health is left, and I end up dying on the Madness Zombies, which aren't very hard at all on their own. Also, remember to use bombs against Wadolf, just try to get above ninety percent in Zamboni, and you get a full supply of them.
Speaking of Zamboni, would any of you think that a high-scores board would do well for it? I reached 100% earlier, and since I'm a whore I'd like to show it around.
