There's a ton here to love, I think it's weird and trippy and unique in its exploration of the "under the surface" theme! I think the art is excellent and the idea of doubling the cover art as a map is wicked smart. Warden advice for portraying the dream world is very welcome and structuring the player experience into acts helps make the volume of information more digestible!
My only real issue is that the text is all far too small to be feasible. You'll want to look into some strong revisions in order to accommodate some of the limitations of print (bleed, margins, etc.). Even if it ends up expanding into a small zine, you've got a strong concept and some strong writing to make a potential jump worthwhile! Good work!
