Hiya, took some notes while reading this, disorganizedly presented here!
don't see a lot of pamphlets eschew writing on their covers, but i think the art and the tagline speak volumes--bold and effective. nice work to artist (for the beautiful piece) and writer (for their restraint!)
presentation is all around very slick. not just in a "wow this is pretty" way -- the way you've chosen to lay out the information is cogent, legible, complete and sinewy. that is not easy!
feels like it bucks the trend of low-information crawls, instead creating a tense resource-management mission. the kind of thing that would be really good to run after one (or more) of the former, to keep players on their toes.
several pamphlets have interpreted the theme as undersea adventures, but (of the ones i've read so far) i think this and one other are the ones that are most "about" the theme, if that makes sense. like the depth is vital to the storytelling. the bends, the cave, mother herself -- all interface w/ the theme beautifully.
this is an excellent work -- confident, unexpected, tight. hell yeah!
