Multiplayer with app is cool, but it needs a controller-only option for single-player.

Needing the phone when playing by yourself is more of a hassle than a help.

Also, it's super annoying that when playing multi-player it disconnects you if you start doing anything else but using the app on your phone. I haven't closed the app, just flipped over to email or whatever, and some of my friends are sloooowwww.
