the boss is more dissapointing than the game
just like others have said get 6 fully upgraded lasersand the game plays itself the only exception being the boss in lvl25 which is flying robotic head that spits out UFOs if yu let the game play itself you will have no trouble getting into the highscores list i just got highest score for the week and i let the game play itself so that just show you how good this game is - i recommend you avoid this one
