This Animation will be the Spiral Door Opening when the Wizard Chooses a World then Walks through. then there's a 2-5 Second Animation you Can Skip with a Little Tab that Shows You Going to the World of Krokotopia. then Once you reach there, The Spiral Door Closes. The Door Wont Open for Other Players on your Screen but will if YOU Go through It.
Probably there's too much coding to change, but it would be fun to have a big reveal the first time you go through the door to a new world. Just the thought of it brings back the nostalgia of going up to the Krokosphinx for the first time, or riding the balloon cars in Marleybone.
I think this is a really good idea! But much like what @Freshta said, it would take a lot of work, but would be excellent as a one-time thing for each world.
