Network representation of the ledge area. It is possible to go from a node to the ones surrounding it using the commands up, right, down and left. The only exception are the red nodes which are ledges. If the character tries to step on one of those nodes it will be automatically sent to the node right below it, characteristic that is represented by the curved links connecting nodes above and below ledges. Yellow nodes mark the entrance and exit of the area and blue nodes highlight the most difficult part of the path. Note that as the original map was composed by squared tiles this network representation is not an approximation but the exact shape of the area
