It started out very funny, then got a bit less funny, and I think it's because it's meant to be read as a whole--I think it would be a lot more enjoyable if 8 comics were posted every four weeks rather than two a week because reading two a week separates them too much....You get bogged down in plot and don't notice the humor.

Also I think it would help if we knew what sort of universe we're set in....Like for OotS, we know what type of jokes to expect, and knowing that it's a D&D parody allows there to be more subtle jokes even if the comic focuses on plot. In erfworld so far, it's just r->w and things like "croakmancer" and the like--nothing world-specific.
