I am still totally stuck. Here's what I can't do:
Get any higher in the bubbles on the far left side of the Veil beyond where the helmet is. Can you go up farther than that? Do you need to?
Get over the hump in the middle of the Veil. Tried from both sides every which way I could think of. Even tried planting spiked plants and climbing them. No luck.
Can't get above the waterfall on the right side and can't get any farther up on the skinny cave next to it. I can only jump from wall to wall twice before I fall.
In the Sun Temple I am also stuck. I got the water to go up a little higher, but cannot go anywhere else. I tried bumbling around in that dark hall but something keeps attacking me and I never get very far across.
I know that this game takes time and must be explored and figured out, but I am really stuck here. I have gone everywhere else I can think of and and am at a real block here. I am starting to dream about this game!! Help!!
