This was fun! The procedurally generated levels were cool, I think it'd be good to have a "continue" or "next level" button that generates another level at the same difficulty.
I played a few games with the difficulty where the wind turbines are placed correctly, and those were easy with a few turbines, and got progressively harder. I tried one game where I had to place the turbines, and that was hard even with 2 turbines!
Overall, I had fun!
