Good for the most part. The game is a good time killer but for some reason I keep running into bugs and glitches, for example for some reason my add timer is saying 7000 hours just to send my vault dweller out thirty minutes longer. Not even that but my ads keep closing and reverting back to my game and it glitches everything. But like I said I love the game, and love playing it as much as I do. But please fix the bugs!!
