Cool concept and some quite fun takes on mechanics. I really wish for for backgrounds to be bit less noisy as i found it a little bit tiring to read. I think map is a good addition but linking of locations could have be bit cleaner, from game mechanic point players would always be moving closer to the final destination so connecting locations on same "tier" feels bit missleading on map. Other than these couple nitpicks, the character mechanics are cool (even if part of me wishes energy heart and supply all had same amount of checks and could be tracked via d8 or d10). Shifting success to 3,4,5,6 feels like a good thematic choice. Very well done.
