Thanks, i thought exactly that before putting it up. To number them. My goal at first was to make that You transport the energy. The blue energy box becomes pink when connected and the door opens. Den you use the transported pink energy box in the next room and connect that with a blue in that room to open next door. But i dident have time to get it working as i wanted. The maze had two new boxes out in the maze. You could not use de blue from the room before. Sorry for the confusion. my bad.
