Take off in a propeller fighter and fight through five stages: lines of fighters, divers that come straight at you, bombers firing spreads, enemy aces, and a flying fortress at the end of every stage. Pick up power-ups for wider guns, extra bombs and extra planes; drop a bomb to clear the sky when it gets crowded.
Works with keyboard (arrows, Space and C), touch (drag to fly) or a gamepad. The guns fire on their own. Free, no account, no download.
