Revisit: Russell, Come Home!

Been thinking about Game Challenge #1: Russell, Come Home!

Here are some proposed changes to the game. 

Reduce number of players from 3 to 2.  Russell and Parents play on the same team now, collectively referred to as the Family Team.

Score is based on a countdown.  Start at 10 points, counts down every time a tree is planted.  That score is given to the Family Team once Russell makes it home. 

Game is played in two rounds, with Player 1 as the Family Team and Player 2 as the Environment.  After the first round, Player 1 and 2 switch teams.
