In the waterfall room, I've been trying to enter both the sequence on the pillar and on the golden door, and neither seems to be working. For instance, my translation of the pillar is (RT = right turn):
RT RT up jump down RT left LT right
I've tried this multiple times, all over the level, and using the D-pad in case I was being sloppy with the joystick; nothing happens. Is something wrong with my translation, or do I need to do something more than just press these buttons in sequence?
