Lancelot: King Arthur's asking you for help with a big, tricky job. You, as a Knight of the Round Table, simply can't refuse such a request! Go on an adventure in a castle full of dangers and try to gather as many coins as possible to upgrade your armour. You'll meet wizards, who can give you temporary protection or other skills. The further you get, the more skills you'll receive that increase your chance to reach your destination!
While playing the game you'll receive very clear instructions. Use the arrow keys to walk. Press the down arrow when you're in front of a wizard and then press the up arrow to receive the skills he can give you.
