Save the eggs being laid in the sky by drawing lines to catch them and guiding them to one of the nests at the bottom (). If an egg hits the ground or your line at too great a velocity, it will crack. If this happens, a mutant bird is formed which tries to fly to the sky. Kill it by drawing a line through it as it flies. If it reaches the top of the screen you lose a nest. The game is over when both nests have gone. Important things: When an egg cracks you lose 100 points. You can't catch an egg if you are still drawing the line (ie it isn't solid until you release the mouse button). The higher up the screen a mutant bird is killed, the greater the points. Shorter lines stay on screen more than longer drawn lines. Good luck.
