operation : survival

survive against hordes of fighter jets trying to take out your anti air guns!!!
right mouse click : right gun
left mouse click : left gun
there are 3 difficulties
easy-medium- hard
harder means less ammo and HP and tougher and faster enemies
it gets harder every 50 seconds
your ammo is limited but you get 20 more every 5 kills
how long can you survive HARD?
feel free to feedback because this is my first game as a beginner :)
