Hey, I didn't think of that, but it does make it more interactive. Just reminder: a Three means the Ghost moves three (and I guess the person whose turn it is, not the roller, can move the ghost since he's basically that piece for that turn).
Two and a half questions:
1) I thought all pieces had to move clockwise. Am I wrong?
2) Can two pieces occupy the same space in the hallway?
2a) If not, then what happens if a player can't move a piece?
