i hate to say it, but i beat this one on easy. i made it pretty far with normal but fuck the blue knight man i wasnt gonna make it. i initially thought i could go back to regular difficulty but jesus this game will crush your head with the strength of a strong, sexy woman with delicious n tender thighs that- yeah this is easily one of the best NES games and im glad i had the chance to play it. thanks @chandler for recommending this awesome game
