## Description
_Navjet_ is a side-scrolling arcade game where you fly an attack aircraft to
defend against enemy aircraft and naval force from a neighboring country. You
start out in the center of the screen with eight lives, and your jet aircraft
in the air over the sea, with the enemy coming from the right side of the
screen. Movement up/down/left/right is allowed, so you can fly back to catch
enemies who passed you, though you cannot move left of your spawn point.
Waves of enemy aircraft start from carriers at your right, and move to the
left and turn at your starting point, to come back from behind you. You can
shoot a gun and drop bombs from your aircraft, and you never run out of
ammunition. When you shoot some objects, you get stars hanging in the air,
which are extra lives if you catch them by flying through them. If you shoot
the stars, you lose them, and get no extra lives.
If you reach the end of the map, you will find the enemies nuclear missiles,
which you need to destroy to get to the next level. You also gain a password
to each level, so you won’t have to restart from the beginning if you restart
the game.
