The creators of Clash Of Clans brings you Boom Beach. This time you're somewhere in the world on a small island, fighting the good fight against an evil army tormenting and enslaving the natives of these islands. Like any other game, you start out small with a few resources but if you have played similar games you will definitely work your way around this and get your base up to speed. The difference from this game to its ancestor, if that is what you want to call Clash of Clans, is that you have ships, ship carriers and of course med kits, flares and bombs that help you once you get to the point of attacking.
My biggest advice would be to fix your gold storage fast. At first it seemed that gold was coming in like water but it slowly slows downs after that. Just make sure to have your defence and storages built up and you should be fine after that. Would this game be enjoyable to have on your mobile device? Yes it would, this game does not require high maintenance and you can just come back after a few hours to see if everything is running okay.
