Very nice idea and the spin actually did matter. I saved my self many times with some centrifugal force pushing away enemies! Thats way I was sad when i figured out that the only time when the energy is restored is when I upgraded max energy :(. One thing I would like is to see the rotation of the platforms when there are no turrets on it. Maybe place some rock or other "background map item". I liked most of the improvements. After all I had good time playing and would try it out more if you would consider developing more.
