This game is relativly easy. It consists mainly of two puzzles. The beginning one which most everybody knows how to pass. (but for those who dont Press 'B' repeatedly) Then the main puzzle. There are three keys and six doors.You only have to have one of the three keys but which one? Be carefull what ammo you use you may need it in the end. Most advanced players should get this in a few tries. Maybe even their first!
