Works best with Turbo Mode on. (see bottom*) Click dots and drag to change the curve. Hold c down while dragging to snap together any dots that the mouse is touching. Use p and o keys to add and subtract points respectively. Warning: It gets very glitchy if you add a lot of points and quality of the line goes down. Each dot represents a point and the color change on the curve represents the amount of weight to each point. *Shift-click the green flag to activate or deactivate Turbo Mode.
