Don’t know who’s house I was in, a friend of my parents I guess. It was before I got my Nintendo, so 4 or younger. The older kids were playing a game on a black and white TV. It may have been Pitfall. I distinctly remember seeing the little guy jumping and grabbing a vine, then jumping in water and swimming. I eventually cried to my mother who made the other kids let me play it. I never did figure out how to control the character, or even start the game.
