Screen upside down

Hello great game you have here at first I downloaded it for free (somewhere) then I read some of your posts and and realized you are a nice guy who developed it alone so I went out and got an iTunes gift card just so I could actually buy this game, but the screen is upside down and I always have my iPad plugged in to the charger so it's annoying and uncomfortable holding it upside down especially with the headphones sticking right into my hand. Is there anyway to fix this? Thanks for the game and good luck!
