Do not watch the 5 videos for the chests,you will not get the rewards!I did love it at one point.I will no longer play this game ever again.I had to reinstall it.It does not link to your google play like all other games.I did not know about the save feature so it took me all the way back to level 1 from 110.The $100 that I spent on space ships and other things was also no where to be found.So I lost my progress and money I spent.Then I tried to contact support and no one ever got back to me.
