Move the mouse around to draw, to pause press the P key and to unpause press the S key. Run your mouse over a colour to change to that colour. Run your mouse over the CLEAR button to clear [obviously]. Run your mouse over the THICK, THIN, or MEDIUM buttons to make the lines that way. DRAW!!!
This is my best Pen game, so please love and favourite if you like it. Please tell me in the comments if there are any glitches. No clicking needed in the whole game!
