This game is a lot of work for no reward. Seemingly the developer has devoted every available moment to coming up with ways to get money out of the player, but failed to consider why anyone would play long enough for that to be an option. There's nothing fun here, and certainly nothing to bring the player back. It's a standard clear the area using energy and only build what we say you can build, when we say you can build it. These are a dime a dozen and there's far better out there.
