Dave, Fist of Odin
I'm down with mad xps, yo. There's a ton more nooks and crannies to poke into, and I know at least one of the books had a stanza where the first letters spelled a word, so there might be other puzzles.
Dave, Fist of Odin is not the thinker of the party, true, but perhaps if we scan around and find some cool shit, there will be a need for a modicum of clobbering. Of course, 'modicum' is outside the mileu of Dave, Fist of Odin, but clobbering's usually a boolean - either you clobber a thing, or you don't. That's how I've seen it, anyway.
On to puzzles! Let's wake that crystal bitch the hell up!
