@Bungie: ever considered to make the buttons to choose the difficulty settings (on the orbit page) with a downward arrow on the right side of the buttons? Just like a pulldown-menu button from a webpage. I didn't know that I could choose the difficulty settings, until I was level 21. You don't have to explain everything and you choose to let users find out lots of stuff, but certainly from a usabilty standpoint there is quite missing a lot of the simple stuff ... Never mind, love your game. Peace.
