Hi Milcho. Thanks for the comments. I did the arrow keys that way because that is the way the old King's Quest games used the arrow keys. It seemed logical to me, because it get tiring holding down the arrow key when you can press it just once to walk.
And to build an ax use: flat stone + rope + stick.
Good job though. Build a hammer with: round stone + rope + stick.
You can also ask the king about quests and things.
Let me know if you have any more questions.
