Black Dot Colorful Lines

"Save the black dot from colorful lines!

Math tells us three of the saddest love stories. Tangent lines, which had one chance to meet and then parted forever.Parallel lines, which were never meant to meet. And Asymptotes, which can get closer and closer but will never be together. And Lines think it's all because of a dot. Maybe it's true but this tiny black dot has nothing to do with all of this.

The goal is simple move black dot left or right by dragging finger across the screen but try not to touch colorful lines while doing so. Simple to start but difficult to master."
