Lines 101 to 108 in ac29ef6

	function repositonGameItem() {
	locationX += speedX;
	locationY += speedY;
	}
	function redrawDrawItem() {
	$("#walker").css("left", locationX);
	$('#walker').css('top', locationY);
	}

@khamal22, just add a basic comment above both of these functions that explain their basic purpose/functionality.
