Use the WASD keys to move Dot around the canvas, and press space to stop drawing but move around freely. Up arrow key = Change the colour of the pen. Left arrow key = Change the brightness of the pen. Right arrow key = Change the saturation of the pen. Make Dot touch the "change background" icon to swap the current background to another random one, or make dot touch the "hide background" to reset it back to the blank canvas. F key = Change the size of your pen. G key = Reset everything/explode computer. Enjoy! :)
RIP to the computer. :)
