Hey thanks for playing my game.
There is no walkthrough but instead I'll tell you what to do next.
(scroll down for spoiler)
Go back to where you got froo
Go north and you'll enter a mountainous area with a lot of caves.
Keep going north and you'll see a goblin, he wants you to get 6 mushrooms, search around in the caves for them
Give mushrooms to the goblin and you get to an inn
Keep going north to the cave of ages
