Arrow keys to move, space to attack, and e to open the inventory. O to use the shield and c to use the bow, you aim with your mouse and when you lift the c, you throw the arrow. B to cancel actions, such as throw a arrow, use the shield, or your weapon. You can use b, too, to go out of your inventory, the map or that stuff. Z to change window (to the right) and P (to the left), to go to the missions or for seeing the actions.
I copied the ideas from The Legend of Zelda, but all of the art is mine.
