Fireboy and Watergirl continue their adventures by taking on a new shrine: the Temple of Light.
The latter introduces a new mechanic: you will have to play with the light by redirecting it, using mirrors, to the detectors of the right color in order to activate the platforms.
Switch judiciously between Fireboy and Watergirl in order to reach the end gates of each level and collect all the diamonds.
