Cheat: In order to easily complete the Kron Colony, defeat the first Kron you encounter. Save the game, then go south to an opening. You must fight another Kron. After you defeat him, with Amy in your team, go to the opening west from that area. Once you enter, bash the boxes with Amy's hammer. Go forward, and ignore the Kron. If you get attacked by him, just flee. Go to the next room. Continue until you reach the ruler, then talk to him.
