The sheer volume of the sound the aliens make when you shoot them was painful. Also the volume during abduction was insanely high as well. The loud high pitched noise continued while on the ship. It was painful and made the game almost unplayable. I hope you don't continue to let that happen in the future games. otherwise it was great!
P.S. I did get hit immediately with a copyright claim, I asked to have the claim removed and was denied, which totally blows.
