I was playing though the game, and I got to the desert temple map. I was at the gold key section, and I got the key. I was going back to the key-door and I got hit by an enemy. The key for some reason fell through the floor and fell under the map. I'm pretty sure it clipped through using the wall crushing trap thingy. It doesn't respawn or anything so I have to restart the dungeon. If this can get fixed that'd be great.
