Oh heck, that new update was bomb! A million fold improvement over the last level!!! I enjoy how much longer it is and how the graphs show the potential for wind and solar power.
A few suggested updates that I am sure you may have considered.
-- Make the replay button actually work (windows)
-- Different difficulty levels
-- Offer "rebates" for energy efficient lights/appliances so the max total power load can go down a bit.
--Population growth that may make the power load increase
--At the end of the game show stats for energy production vs consumption and from what sources.
Thanks! Keep up the great work
