I like where you chose to make the camera zoom out. The breakpoints are somewhat gradual, but by the time the second one occurs, you feel massive. One thing I noticed was about being big was that rotation is a little too fast and jarring especially when compared to the way you accelerate forward. If I were to make a suggestion, it might be to make pressing the A and D keys add torque to the player's plane instead of setting the angular velocity. Also, I believe there is a bug where the score doesn't reset when you press "Retry". All of that being said, I enjoyed playing this game.
