absolutely love the game mechanic even though they are objectively dull. also there is add that take 3-5 clicks to get rid of every 1 minute so the game isn't a game is a large ad that you get a mini game break between the gigantic ad breaks because that's all there is ads and more ads, if you love not being able to play because of ads then this game is for you! Great potential, ruined by GREED WITH NON STOP ADS 80% is just ads, the rest you have to quickly hurry before your 20% of time is over

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.

Ive played for a bit and im starting to enjoy the work I have done so far but # stars seems resonable because the money growth is vary slow. Update- I just got my 20th rebirth and i can get another rebirth in under 10min, and with the purchase of the big square island it makes progression much faster and constant, and now I'm giving it a 5 star because I have learned how to manage my money better in this game.
