Newton's AG

There are two teams: Blue Squadron and Red Squadron; Blue Squadron to shoot first. Set the "angle" of your mothership by pressing on it, then set the power by pressing on the energy bar and then shoot by pressing on the red (fire) button. Before you can destroy your opponents mothership, you have to shoot down the spaceships. Stars have gravity fields able to divert your projectile; planets have no gravity fields but they orbit around stars. Enjoy! ;-)
