The directions are more elaborately discussed when you click the green flag but here's an overview: left and right arrow keys will tilt the plane, up and down arrow keys will alter altitude, space changes the thruster power (speed), the x and c button relates to the weapons (guns and missiles) the aimer is controlled with the mouse, click to shoot (the weapon must be locked). The instruments on the bottom shows the different variables. I had a hard time using scrollx on the outside (the sun/terrain) so that aspect is unrealistic, but the instruments work to perfection! Anyone can remix it (try to fix that x variable problem) IF IT SEEMS REALLY SLOW ONLINE, TRY DOWNLOADING IT.
