The brush follows your cursor. Click the eraser to erase the canvas. Press the right arrow to change the brush height, width, size, or paint color. Use 1, 2, 3, 4, 5, and 6 to change the background. P.S. : Don't move your cursor very fast while painting to keep the paint strokes/dots together, but if you need to move your cursor into a different area such as writing words then this can be helpful.
