press space to change the color and size. press space again to hide. after you press space to hide, you have to wait 1 second to press space to change the color and size. mouse down to draw. if you are drawing and your mouse touches the erase button, it erases. (i could not figure out how to fix it) when clicking the erase button, set your size to 0. (do that so it doesent draw behind the erase button)
