The game would be nice if it wasn't build that it's impossible to play it without spending real money. Everything you need to progress in the game requires quite a lot of energy that you use up in a few seconds, no matter how strategic you are and then need to wait another 24 hours to get your energy replenish and even that doesn't get you bars minimum. No matter what you do, unless you spend money, you virtually can't progress and get stuck. Don't waste your time, it's not worth it.
