On level 3/24
Not super balanced. On Hard the first five levels were a cakewalk. Then it became impossible and really quite exhausting/annoying. By level 8 even normal is a pain as your towers are constantly exploding. Then you cant use shields and repair at once, though no one ever tells you this. I had EM pulse for 5 levels but it was unnecessary as the bad guys dont get shields until mid game. This was sort of fun, but I wont finish it.
