Mutation modification testing notes.

Quick mutation update ideas before I forget them like last time

STRONG DIE = same level adjacent dice < current level
WEAK DIE = same level adjacent dice >= current level

Only weak dice can be stacked on.
When doubles are rolled, player must remove if possible and it's any birds eye adjacent STRONG die.
May reroll double only if no legal removals.
Don't place a die on a turn when you remove one.
Give removed dice back to opponent
Game over after any player places their last die.
