In this game you have a bigger bird (probably a kiwi) and a number of chicks. You move the bigger bird with the mouse. When you press space a circle is created around your bird. This circle stays in place for a couple of seconds and then disappears. If a chick enters the circle before it disappears, it creates its own circle that works the same way. If another chick enters it, the reaction continues. Your goal is to catch the required number of chicks in each level "detonating" your bird only once.
