The purpose of this game is to EXTORT money from you. It would be a fun game if it didn't require so much energy to do one thing. I have 87 max energy but it cost 158 energy to chop a tree down. You can make different food items to get more energy but 158 energy to cut down one tree. Bushes uses 25 energy and you only get one flower from the bush. You need 30 flowers to fix the bridge. So, you'll need 750 total energy. You can buy 1500 for $2.99 & the price increases.
