0.2 Mouse hit test for the circle

            // All the same from above as 0.1
			
			createjs.Ticker.addEventListener("tick", tick);  // Add a "tick" event so that the function tick(){...} runs periodically
		}

			if (circle.hitTest(stage.mouseX, stage.mouseY)) { circle.alpha = 1; }  // If mouse hits the circle, change the circle colour to solid
			stage.update();  // Draw on canvas (notice it needs to be updated constantly so we did not draw in init() function cuz it's pointless)
