Get the Power Bracelet that allows you to kick blocks. At the main screen where you can choose to play a new game or continue, kick one of the blocks to reveal a passage to a secret room. Save two keys from the fifth geyser, and use one from the stone circle under Gruk's house. When you complete the game, go to the secret room, and you can open the door. A man will open the middle door on the new game/continue screen, which lets you start a new game with all your previous stats and items.

To unlock the secret start, you must have beaten the Fifth Shadow Geyser (with at least one extra Star Key), and beaten Agram. Without turning off the Gameboy, in the circular room, kick the box in the bottom to reveal a secret stairway. Go into the next room and talk to the man in the room to unlock a secret start!
