Instructions
Stand on one of the pressure-sensitive floor tiles. This will pause the blinking floor tiles leading to the crystal in place.
Step off the pressure-sensitive floor tile just before the blinking tiles to your right reach the same position as the tile you have paused. The two paths of blinking tiles should now reach the center crystal simultaneously.
Step on the pressure-sensitive floor panel to the left of the one you just activated to pause the blinking tiles in front of it.
Step off of the pressure-sensitive floor tile just before the two synchronized blinking tiles to your right reach the same position as the tile you have paused. Three paths of blinking lights should be hitting the center crystal simultaneously.
Step on the pressure-sensitive floor panel to the left of the one you just activated to pause the blinking tiles in front of it.
Step off of the pressure-sensitive floor tile just before the other three synchronized blinking tiles reach the same position as the tile you have paused. All four paths of blinking tiles will then reach the center crystal simultaneously, unlocking the door to the next Challenge Room.
