I like it! Personally, I could see it being more challenging, with termination points all around the edge of the screen, and challenges such as use 3 junctions, less than 20 units of wiring, etc.
Great job!
I think this is about as perfect as I could do it - Maxed population, only 7 extra food, 3 extra water, and 2 extra energy.
It only took over 2 years in sandbox mode. :)
GREAT GAME!!!
