I was really enjoying this game (really nice graphics and nice descriptions), but now I'm stumped.
I have the silver coins, snake skin, shells and small cauldron that I can fill with green acid or rainbow-coloured fluid. I can't work out how or where to use any of these items. I need a disc to insert in the mechanism near the volcano, a way to open the door at the base of the mountain and a key to enter the pyramid. I'm also sure that I need to do something with the well at the base of the mountain, the deep pit at the volcano and get the scorpion in the desert. There's also a horned ram, an owl and a noble stag that may have some relevance at some point.
I've been trying brute force with every verb I can think of with every item in every room, but all to no avail. Can you give me a hint, please?
