Puzzle elements


As you enter the puzzle, you find a red emitter, a red receiver, a connector, and a green receiver. The red receiver controls access to another area to the left. The green receiver controls access to the progress wheel.

In the area you enter on the left, you find a twisting passageway, with a blue receiver immediately on the wall on the left. The first room in that passageway is blocked off by a blue door deactivated by a pressure plate. There is an inverter available. At the end of the passageway is another small room with an RGB converter inside that is blocked off by a blue door deactivated by a red receiver.
