Use the mouse to move. In this game, there is an invisible object. Each time you find the object and click on it, you will get a point. The points are displayed in the top left corner of the screen. Since you can't see the object, music will be played throughout the game, helping you find it. As you get nearer to the object with your mouse, the music will get louder, so while you are moving your mouse across the screen listen to when the music is at its loudest, and when you are sure you know where the object is, click the screen and find out! If you managed to find it, you get a point and the object moves to a different place on the screen. If you don't, then try again!
