Allowing the king to win only by reaching a corner square actually seems to make the game unbalanced in favour of the attackers. Only twelve pieces are needed to completely seal off the corners. With another three pieces left the attacker can create a line to sweep across the board, gradually constricting the king's forces. There appears to be no way out of this for the king.
