	Nature in this world is out of control!	
	
	Stop the trees before it is too late.
	
	Brick and other solid tiles are resistant to the wild growth.
	Concrete has double the durability of bricks.
	Refined Concrete has three times the resistance of concrete.
	
	For your effort to colonize this overgrown planet,
	the Choppy Co. pays you a coin for each tree you defeat.
	
	Also, do not loose the market..
	
	Good Luck & Much Chop
