I doubt it actually is the world's hardest game, but it is definitively challenging. There is also a sequel.
i used to play this back in high school i beat it lol
Oh, this game? Most amusing part about this game is that it doesn't even come close to being "world's hardest".
This is old news, and definitely not that challenging in the scheme of things. :-\
