Welcome to my basic drawing program! Here is a quick rundown of the features. - Size Changing: Use the up and down arrows to change the size of the brush. - Color Changing: Use the left and right arrows to change color. You can also use the r key to toggle constant color changing. - Auto Draw: Typically, you have to hold the mouse to draw. Using the d key, you can enable constant drawing. - Brush Changing: Use b to change the brush. The brushes available currently are a square and circle brush. Changing brushes will disable auto draw. You can still re-enable it. - Canvas Clearing: Use c to clear the canvas.
