Zoch Off through the wall

In this castle, things are spinning: the floor rotates. Ghosts dance through the walls. As if moved by ghostly hands, hats and shoes flit from one bay window to the next. During the Carnival of Ghosts, everyone wants to haunt the corridors in the boldest costume. But even the costume rooms suddenly aren't where they just were. The winner is the one who visits the various rooms of the castle and collects the carnival costumes laid out there.
