Use the mouse's right button to select the correct (edible) object and get scores. Collect as many scores as possible in the allotted time. Objects disappear if you do not click for a long time, and you lose some scores. Shortly before disappearing, edible objects are highlighted. If an inedible object is selected, a life will be lost. Losing all lives will result in losing the level, and all scores will be deducted. However, you can always try again.
