So far so good I like the story the graphics and the missions... EDIT: Well, I have been very frustrated with this app. The amount of free energy is ridiculously low. It will give you less than a minute at a time to play. And buying energy it is also very expensive considering how quick it get spent, I don't want to spend 10$ just to add a couple more minutes of fun and that is it. You can't finish the events without expending a ton of money...
