After climbing the tower, collecting all the pieces and getting back to the top the game isn't over.  You must climb the dark tower.  Everything inside is reversed, the shadows are white and the background is black, so it may take a bit of getting used to.  The levels also introduce spirals exactly like the shadow corridors used.  At the top players are forced to run from the shadow monster for a full two levels to escape.
