I have sack, gold piece, sliver coin, rope, branch, silver key, sword, shovel, hammer, nails, bow, arrow, fishing pole, club, ticket, sunstone

I couldn't find anything in the cave to dig. When I gave the gold coin to the soothsayer she didn't say anything new, so I restarted the game. Then when I got the gold coin I went to the garden maze thinking I would be able to pay the toll, but that didn't work, so I went to the store to buy something, and that didn't work either. So now I feel stuck again. I can't get anything from the store, I can't get into the white tower, I can't do the garden maze, I can't use the boat, I don't know where to find a castle or a volcano. And I still can't find that stupid diamond!
