Hey there.

So I have been racking my brain over this game I cant remember. It was a futuristic Nes game. I remember it being about a man on another planet or fantasy world and in one scene there is a black tar slick slime creature gets the man, he dies. I remember it being a difficult game for me, however I was like 8 or 9. Cant remember the name of it for the life of me...can anyone help me?

Thanks in advance.
