Sentinel Returns

------
At first, you start off with only 10 units of energy, 
represented as 3 robots and a tree. You will have to be 
able to calculate the amount of energy you have at a glance.

Since each tree is worth 1 point of energy on the landscape, 
each boulder is worth two, and each of your robots is worth 
three, that is how your energy is represented. A gold robot 
is equal to 5 normal robots, or 15 units of energy. The basic 
guide is simply to look at the amount of robots you have, and 
multiply that by 3.
