Yeah, yeah, I know its crappy, the lines arent smooth, but I tried. Anyway, you are a little octopus. It follows the mouse pointer, and whenever you press space, the little guy leaves a line of ink in the water. you can change the color of the ink by swimming over to those pretty little colored blocks. A blue block will turn the ink blue, the green block will turn it green, I think you get the point. Too slow? Press 'b' for a speed boost (Note: If you hold b while drawing a line, it will look a bit choppy)
