I dont think that what you're grandfather did was, you know... "Yaysers". But i understand that in that position you have no other choice than to do what he did so it was not the wrong thing to do. :)
I cant say much about the animation itself as it was pictures with animated details, but the pictures where of star quality and the story was heart touching. Therefor, I vote 10/10 and 5/5. -thumbs up-
And NES is the shit.
