The cursor will sometimes go through the noodle because physics engines have a hard time keeping up with computations for fast moving objects. I could improve it and make it work better on a PC game but for a Flash game, it would lag up because of too much computation while doing the physics calculations.
I know the game can be quite difficult. Using smaller and slower mouse movements will allow you to keep the noodle from launching all over the place and slipping away.
