The Spiral Door is long due for an update. I suggest a map of the Spiral that shows where the worlds are in relation to each other. Worlds the wizard hasn't unlocked yet can be blacked out with a question mark or not there at all. To travel to a world, all a wizard has to do is click on it.
That would be intresting same sort of idea as with pirate101. Maybe make wizards walk through a spiral corridor and chose the door they walk into. Kind of like a main sky way in pirate101
Mass Effects.... how they have it set to travel planets by showing the massive universe and you select which location.... make it where once you done the story of that world you get precision spiral door, that instead of entering through the spiral door, you can enter to any area (with access) instantly
