Game straight up doesn't work. When I start up the app, im in the tutorial, I place the first windmill, but when the game tells me to sell my energy, it doesn't let me. I figured I'd close my game and re-open it, but when I did, it took away my energy, and I have no money. Can't even afford to restart my turbine. Tried deleting and re-installing, same issue on repeat.

Started out okay, but after a very short time it got extremely repetitive and boring. There is no storyline whatsoever so all you do is build a few things, wait until you get money, then build some more. A poorly executed tech tree makes an attempt to keep ones interest but, like the money aspect, the science is just gained and used in the same manor over and over. And then the constant need to see the Facebook link as well as "offers for a 'great' deal for only $6.99" and it looks like a cash.

I like the game. It's cute, simple, and fun. But holy cow this app is filled to the brim with ads. Honestly, you don't need to constantly bombard me with offers to pay real money for things. The ad at the bottom of the screen, really? You make me watch 4 ads in a row to remove mountains or forests, you randomly pop up an ad after saying "A word from our sponsor" and also constantly bug me to pay cash for expansions or resources? The game is fun, no doubt, but it's ruined by the adpocalypse.
