I remember playing old french game "Metal Mutant", which on a level three or four asked something in french (it was probably asking for a code from manual) and if you answered wrong, it wouldn't exit the game, but it'd just silently disable all projectiles, making game unwinnable. I as a kid spent hours wandering around, thinking that I missed some clue. And game didn't have any saves, so after banging my head for a couple hours, I'd exit game frustrated, and in a month or two I had to start from scratch if I wanted to try to complete that level again.
