I have been in the earth temple for weeks!! Help!! I can't seem to get my shield high enough so that it can reflect the light onto the two top sigils. I have Medli standing on the tall platform reflecting her harp onto Link, who is on the shorter platform facing the sigils. I've destroyed the two lower ones but can't reach the two top ones!!! It's been so frustrating!!! It can't be that difficult, can it??
