Ok, I am at Dante the Tatooed Man. I know to flip the switches on the bottom, and roll the arrow over the puzzle pieces to make them change to what I need them to be. However, when I get to the last piece, I cannot get just that last one to change. And then time runs out. I read in the guide that if you hold the right mouse button the tile won't change, but if I do that, and let go when I'm on the piece that I need for to change, it doesn't change either. HELP PLEASE! I am so stuck.
Thanks!
