Swear words wont describe the difficulty.
Like all games in this series, you have to go through the game twice to get an attempt at the last boss...this I can handle, however what sets this game apart from its predecessors is that the last area is 99% impossible with the weapon they require you to use to reach the last boss.
If anyone out there has beat this game without cheating, congratulations, you did something I could not. I simply could not kill the gate keeper with that low range piece of crap weapon you use at the end of the game.
If you owned this game and didnt throw your controller at your super NES at least once, you are a saint in my book.
Anyways, other than that, its your typical side scroller, good graphics good sound for an SNES game etc.
Check it out, but dont be bent on beating it without a cheat.
