Hardly... did you beat MasterNinja?
Strangely enough, I got within inches of it. Thing was though, by the time I had gotten all the way to the end on Master Ninja for NGB (which was evil-hard!!! And just plain malicious!!) and died, i had been playing the game for so many hours mastering it, that I got bored and ceased to care. I knew that I could do it, and needed a break from the game. Life was busy and I never went back to it.
Good Lord that game was hard!!
NG2 is even worse. 99% of your deaths are from some dingus shooting fire at you from off screen. Really wanted to slap Ita for that one. Was just plain cheep. I think I beat up to the second or third to last difficulty, and just stopped due to how cheap it was.
