No need to feel sorry. I never had a NES, I was actually thinking of Super Mario Land on GameBoy when I wrote this, but ultimately wrote it a bit more generic...
I do however have a vivid memory of LucasArts' Indiana Jones and the Last Crusade, where I got stuck in a cave under a Venice Cafe for days, because I didn't know that I need to talk a guest out of his Wine-bottle using specific sentences, and use the wine to soften the mud of a lever in a wall...
But I guess that's too specific for anyone to relate to...
This is one of three things I would time travel to tell my childhood self.
