After reaching the end of the 6th part of this dungeon I get told to go get a key if I want to fight the boss and so I get it from the Lucy girl and then I go back, use the key, and on the bridge to the boss the game just doesn't let me walk anymore so I just sit there listening to music. Irritating. Edit: I decided to go back and finish it again and now they want me to pay 7 dollars for a bridge and choosing ads means I have to watch over 20? Quit it.
