So just before entering the platform jumping hall of the ghost that died looking for "the flower that doesn't exist" there is a pedestal. Reading it gives "Sometimes the only way forwards... Is Backwards" So I proceeded to walk around the whole dungeon and into walls backwards but to no avail. What on earth does it mean!
Also does anyone know where "Flora" is? She wants her pearl necklace back but I can't find her anywhere any more.
