That would be King's Quest 3, my first and last for the next seven years. I will explain.
I was very young when my mom got her Atari. She would use it to compose letters and write harlequin housewife sex screenplays; I would dive eagerly into the trove of pixelly adventure games and bewildering text adventures that came with. My favorite by far was King's Quest 3, not only because Alice in Wonderland would never move or open doors or eat her cat like I was telling her, but because I was also by that time well obsessed with folklore and fantasy and mythology. And it had wizards! And kings! And cats! Hooray!
So I booted it up and poked around. I found myself in indentured servitude to this absolute asshole of a wizard named Manannan. He told me to do things and got angry when I didn't. He was like my mom, but with evil magic powers. Bleah. But then he went away on a trip, leaving me alone in his house with all the cool stuff and the way out all unguarded. Now was my chance! I stole everything that wasn't stapled down, fell down the mountain a few times and then was free! I wandered about, got bored, and decided to go home again, only to find that asshole wizard had returned and was right pissed off about all the stealing and escaping and stuff. So he did what asshole wizards are known to do in these situations, and zapped me down to a pile of ash.
I feel I should mention that I was at most six years old at this point. I was a tiny girl who loved her teddy bear and played with Barbie dolls and wanted to grow up to be Jem. The little pixelman on my computer screen wasn't a poor representation of some fictional ruby-skinned other kid, he was ME. And I was a pile of ash.
I ran away crying. And never touched another video game for years after. And I'm still actively scared of dying in games, to the point of turning off the console or closing the program before the fiendish death animation can occur. It took the lucent swooshing of Star Fox to lure me back.
Fucking wizards.
