Honestly, I LOVE playing the game...that is, after I've spent a few bucks here and there in order to buy energy to make any sort of progression on the island adventures. I'm beginning to realize that the amount of energy it takes to make the supplies to upgrade anything in this game just doesn't level out with the benefits of the upgrades. I would've given this game a 5 star rating after first downloaded, until I realized it was just another "freemium" app. So, I generously give this 2 stars.
