With around 700,000.... And if you can get a rythm going and not die, the points start adding
I made it to somewhere over 1.1 Mil... but now I make stupid mistakes just around that time.
I suppose that is just the next rung in the ladder.
I'm guessing you get to a point where it doesn't get harder and you can rely more on a pattern?
