Great concept, solid gameplay; it is important to remember that the
Demigorgons, or Medusas, cannot protect other pieces, but as Immobilizers,
will petrify anyone who moves into their space, captures and thereby comes
into direct line of sight of them, or sits adjacent to them.  Calculations
of strategy must therefore be modified during play--sections of the board
may be closed up by frozen pieces, and that makes the whole game exciting
and tense.  That same 'closed board' may fly open in the later stages of
the game.
Thanks, Ed--job well done!  Skeptical?--try one over the board with a
chessfriend!  See for yourself.
