Forgive me if this is not the best place for such a question, but I figured with all these retro games popping up (like LED Football), folks might remember this one... It was a game that I played in college (mid 80's) on my friend's Macintosh. It was a black and white game that was a bit like Myst in that you walked through the world, scene by scene, by clicking the mouse and it would advance you along the sidewalk or wherever. The story had something to do with a vampire that I think you were trying to avoid by avoiding nightfall? And it was a puzzle-solving game, again much like Myst. Ring any bells? I would love to see that game again - I just remember my roommate and I being hooked to it for a bit.
