I keep my iPad orientation locked so it's landscape and I can hit the home button with my left thumb, while mostly typing with my right hand. I've seen a lot of right handed folks do this.
Fast Striker is upside down like this, and it lacks any intelligence to determine how the device is oriented.
So the iPad has to be turned 180 degrees to play, then 180 degrees back after. Not that it matters much. I deleted it after a couple days. I'm hoping the MVS version is Bette. This seemed pretty dull.
