Try going up the stairwell you came out of in the first castle, where the game started. The game will not allow you to ascend. Press F11 and go all the way to the left of the screen. A screen will appear with cheat mode options. Note: You may have to move a spot or two in the corner to find the correct location.
-Once you exit the first castle (the one you started in), head straight down and you will see a peak of land. Enter into the water where the longest part of the peak ends to fight Death (which is an easy battle). Note: To restock, go back into the water and you will not have to fight Death again.
-When you leave the first castle where you begin the game, before moving west to the cave, go south to where the water is located. At the rightmost south corner, you can enter the water and fight a small drawing of something that cannot seem to damage you. One hit will kill it. You will get an incredible amount of experience points. When you fight in future battles, you earn a level for each fight. This stops working after awhile.
After you fight Salander for the first time you will come out of a hut. Go southeast until you come to some trees, then go northeast to a peak of land ending at the water. A voice will tell you to go to the royal hut. Go eight west, six north, four east, eleven south, four west, five north, and six west. Do exactly what the voice tells you to do.
