I have all the keys except one. I know where to get it but I do not know how. The place where you get it shows up on the map on the 1st and 2nd floor. Recently I asked a question about a room with a dragon's head and tail. In the left corner of the whirlpool room is it looks like a door. I have studied my map carefully and that makes me think that door is an exit. How do you get in the other side of the door? The only thing left in the whole temple is the boss key and a regular key to get in the door with the boss key. Maybe that will help. Thank you for your help.
