I've updated the demo to include the Central Village zone, that includes King Harvine |||'s castle and the termites nest. I've also fixed a bug that was crashing on map change. The reason for the crashing was in the new "game engine" interface. I hope everything works this time.

By the way, the steps that are revealed with the flute can be traversed just by standing between the wind pillars.  Central Village (zone 3) is missing some things. There are 2 entrances to it, either though the fountain room, or through the large open room in the Garrison.
