In order to prevent the upper levels from being clogged up, perhaps I
should introduce a gravity rule: before a player moves, all of his/her
pieces that both (1) haven't moved in the past two turns and (2) have an
empty square directly below them descend one level.
Or perhaps, when an elevation isn't possible, a 'captured' piece could be
placed on any empty square chosen by the capturer.
