Does this game have an End or does it just keep randomly generating levels until you quit playing? I can be a little OCD with games so I got to 1,111 before I gave up. If they are randomly generated you might consider working with the generator a little bit because most of the levels are passable simply by staying at the bottom of the screen.
I have a logitech mouse with ball bearings, the mouse wheel can spin for almost 2 mins with no help. Combine that with rapid pressing on the laptop left-click button and I got a score of 45,651,056
