The map is my favorite piece of visual design here but the rest of the project manages to feel very authentic to the 70's - owing to subtle use of textures and a great font choice.
It's proper weird in just the right way and the creatures in particular, !Polyphemus!, are a joy.
Layout/formatting is where my only nitpicks come from as some of the blocks of text don't have anything to draw the eye to pertinent information, rather you just need to read them front to back and maybe more than a few times if you're anything like me.
