8000 energy to complete a board!!!!! I have spent way to much money on energy. It should not cost 300 energy to get past a car. Or 190 energy to break metal that you barly get enough of. You can watch adds but it gives you 100 energy. Plus when your upgrading a building they requier you to make something from that buildind to progress. So your forced to buy gems that cost an obscene amount and they barely give you any. The amount of money that it cost you to play this game is ridiculous.
