figured out you can't return to the temple if you have the cup in your posession (you have to return it to the ground to go back)

-get stick from water tub thing
-go back to desert world and make sure you have stick highlighted when you stand under "blistering sun"
-return to temple and go to water world.
-put stick in water "ring" thingy and it will expand
-now you can put the stick in the "Bed of strength" back at the temple.
-this causes silver hammer to appear in bath/tub thing
-get woven plate from pillar (i think it's the left pillar in the main doors screen)
-use hammer w/left pillar in the "altar" screen
-pick up dirt w/plate, offer plate to desert door and you will get i believe the silver shovel
-use shovel with dirt under cup in the desert world
-you will get a blue sphere, put this in the altar

you have to double click it while you are under the "blistering sun" in desert world and you will watch it dry.

-use cup from desert world to get healing water from temple.
-use the now filled cup on the Bed of Strength's hammer stick to add salt (salt comes from stick drying from the salt water).
-Offer this now sea water filled cup to water world door, you get container.
-use container to grab wind from water world (appears as twister in one of the screens).
-add wind to altar (you get 2nd step)
-before you "fall down" behind second step, make note of code on one of the temple pillars, these are directions (right, left, up, down, left left) - you will see 8 dolphins
-go back to beginning (click woven plate and click "the end")
-now the full pillar code said: right, left, up, down, left left, e e
-"e e" telling you to rotate the code east: so reading from bottom you get:
up, up, left, right, up, down
-get flame w/container, you can only go left now
-offer container to pillar, go right and get flame again in container
-go back to templer through pillar, offer flame to altar
-you now get final step and go up and get magic sphere
-go back down and put sphere in main doors and enter dolphin codes (#'s were in water world, desert world, hell, and pillar view where you crushed the stones w/hammer -shows up only now)
-if you don't put sphere in main doors and decide to go to earth, you get just okay end.

water tub thingy? I can't seem to get anywhere apart from the desert, then I can't get back whether I have the cup or not

I had no flame with me from hell, I missed that you needed to get another one after the offering.
