Didn't know that, but not surprised. When I got to play with Hypercard in elementary school, I drew houses and paths and put buttons on the paths to navigate between the screens, with some text to tell a very simple story (wish I still had it, but it's long gone. I only vaguely remember what a couple of screens looked like).

If I had more time with it maybe I might have been able to turn it into a proper game. Not on the same level as Myst, though, of course.
