I really like the quality of the artwork. The style is not my favorite, but it probably will be less distracting with time. The 'w is the new r' speech-motif is off-putting to me, as are 'croakomancers' et al. They both feel like contrived silliness, whereas I prefer silliness that comes off as more organic. The dialogue of OotS often comes across as 'the player says this in character, forgetting s/he is speaking in character', which is a funny break of the 4th wall for me. By comparison, the dialogue of Erfworld thus far comes across as 'the player says this in character, thinking it'll be funny to make the characters talk like this'. Thus far, the latter approach is rather scattershot in its success. Finally, jokes that take two or three strips to develop worked well when we got 6 strips in one go; they'll be a much tougher sell with, IMO, smaller returns if we have to wait 5 days to get a joke. I put myself in the 'I'll check it from time to time' category.
edit: Realized why the plot felt familiar: one of the vignettes from the original Heavy Metal movie had a plot that felt very similar, to this point.
