Try to go 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], then 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.
Press [F11] during game play to walk through walls, walk on water, walk over lava, and walk past other obstacles.
Quick level ups and extra money:
As soon as you exit the first castle (the one you started in), go straight down and you will see a peak of land. Enter into the water where the longest part of the peak ends. You will fight Death (which is an easy battle). Note: To restock, go back into the water and you will not have to fight Death again.
After defeating one of the element creatures in the Element Trials hut, talk to "?????????" (the black figure) to get your party's life restored.
The Sword of the Gods:
After fighting 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.
