As the game is programmed, pawns and kings can be mystery pieces, and since it tracks the mystery piece through its location, a promoted pawn would still be a mystery piece if the pawn was. Whether this is per the inventor's intention is another matter, since he didn't program it. Since checkmate has to be done with the assistance of the mystery piece, choosing the king would have the disadvantage of the king being less mobile and so less capable of assisting in a checkmate. Choosing a pawn would have a similar disadvantage unless it got to promote.
