I'm a big fan of your work. I feel like the ship can get destroyed too many times in a short time. I got caught in the cross section of lasers, and lost all 3 lives in seconds! I also noticed that the help text is still the phone text, and clicking after you've lost all lives will show the ghost of a ship.
