Navader is a Space Invaders derivative. You're a green butterfly and you shoot other green insects. The game has two modes, unimaginatively called Game A and Game B. Game A is your basic Invaders game. It's not a faithful port nor it's meant to be one, but the basic ideas are the same. You shoot only one bullet at a time, the enemy formation moves one step at a time, they come all the way down and you lose. Game B is more chaotic. You have rapid fire. A random enemy will be selected to attack and flash red, and it will shoot a long laser that destroys everything on its way including other enemies, long live friendly fire.
