Once you are on the last floor of the temple before the boss, look at the top screen. There should a key icon there. You need to hit a switch somewhere on the floor and the door blocking the room with the key will go down. After that, go grab the key and leave the room. Now, if you look at the room the key was just in, there are swirly tiles. There's swirly tiles in the hallway too. To get the key to the door successfully, you cannot step on any of the swirly tiles in the hall. When you are at the door, just tap the door.
you got to hit them with your sword and dont let them take the boss key
