What's the hardest game you've played?

I beat that game The last boss was hard, as was pretty much the whole game, but once you get the pattern it's not too bad. I think I am the only kid in my school to have beaten that game. Everyone else just gave up.

I am not really sure about the hardest game I've ever player. IWBTG was pretty hard, but it was all about memorizing patterns and timing your jumps. I have seen the hardest game, though, on YouTube. I don't remember the name, but it is an arcade overhead vertical shooter and the last boss pretty much covers the entire screen with each of her different attacks, giving you about 2mm of space to manauver, all the while you are trying to shoot her.

You mean this boss?
