I have spent large amounts of time this summer constructing the ultimate map for this game. I'm currently halfway through chapter 3 and it's looking pretty good so far. I'm print-screening each room from the map, making them 50% their original size and putting them next to each other in a way that changes the perspective of the game all together. I'm also doing this with areas outside the map (Figure Space, path to earthquake trigger), the menu, credits and the extra chapters.
Some areas like the Infinite Darkness and other dark areas don't benefit much from this since you can't see anything anyway, but i wanted to do this because it really changes the way you look at the game. While putting together the map I'm also marking the hidden paths between rooms and such with green lines.
Because of the massive size of the entire map I've divided it into six smaller parts. One of these parts, the lower right one, I recently finished. I've put it up here for you to enjoy, sorta as an appetizer ;)
