It's World War Two (or something) and you are a rogue fighter pilot shooting down anything you see in the sky. Choose from 4 different Barons to play as. Press up arrow and down arrow to go up and down respectively. Press 'x' to fire your machine gun. Press 'z' to reload. Don't crash into enemy planes or you blow up. Don't let 5 planes pass you or you blow up as well.
> UPDATE V1.1! < Now with a retry button! Finally! Also, I have a shorter intro because you complained about it. If you think the planes look familiar, it is because I have pretty much re-skinned the plane from the mobile Rovio game 'Retry.' Music is 'Ride (Flight) of the Valkyries' by Richard Wagner. All sounds are from Freesound.
