This is really great! In "Rotate System CW" mode the controls are as precise and intuitive as you can get on anything other than an arcade cabinet or Atari console (neither of which is playable during a commute). The crank position matches the paddle/vaus position 1:1, and the A button is perfectly positioned for firing when you have the laser power-up.
My only other suggestion would be to have the game area take up more of the screen while in Rotate CW/CCW mode (there's a lot of empty space and redundant logos). That would make the it pretty much perfect.
