This is a great game.
However, after a few plays the player with a more offensive strategy (pushing their nearest pieces forward) seems to leave themselves vulnerable.
It appears a reasonable strategy is for a player to get a gap on their backrow by just moving one or two pieces forward, and then osscilate the remaining pieces (such as the 1-ers) on the backrow waiting for the opponent to make an error when coming forward.
This has lead to both players not moving forward and osscilating bits on their backrow, a form of stalemate.
Not repeating moves as a house rule is not an option, as you can get several pieces on your backrow for this purpose.
Is this a problem? Or would you think this house rule could solve the problem?:
'The last piece a player moves (whether the original piece in a one-piece movment, or the last piece in a bounce move) cannot ultimately come to rest on the moving player's shore or a row closer to that player.'
