So a lot of complaints about the instructions. I did read your instructions, but they are not as clear in the beginning. Later on you understand it. I do not really mind the lack of it, though it would have been a welcome addition.
In the beginning this game is pretty hard. actually the game gradually becomes easier and easier, depending a bit on your upgrade decisions.
When you bought 2 satellites, you could just close that station down by letting it overheat.
you could ignore the generator power upgrade, so to make the game easier. I did this in the beginning, but loading the beam would take ages.
The capacitor upgrade became very expensive very quickly and although I had a lot of cities to destroy, it wouldnt let me destroy big cities, so money was coming in very slowely.
When I was saving up money I also would let my research lab get destroyed.
after a while I just figured it would take ages to get the money and I started upgrading the power quite a bit. It definitiely became harder, but not really. at that time I was already bored with it.
at first glance this looks like a very fun game, somewhat complicated, but soon you notice that its pretty easy, but very boring. I think I would have enjoyed this game much more if you would earn more money and the world had lesser cities. No way that I was going to finish this game. I cant imagine anybody did. Not because its not possible (its easy), but because it takes ages.
