I have a lot of nostalgia for this game from when I first played it as a kid. I wasn't quite old enough to have played the old purely text-based Zork games, so this was my entry point. It definitely was a unique entry into the point and click adventure genre. It has an element of puzzle-solving and a kind of creepy, quirky vibe that stuck with me. And some ridiculous humor. The soundtrack was haunting and is memorable to me. Also, as primitive and grainy as it may seem now, at the time this and Myst basically were cutting edge graphics.
Of course, like a lot of older games of a similar enough genre, there are numerous ways one can simply die by making the wrong decision. I remember bringing the game up to an older gamer friend of mine and he never got past a rather early point in the game (trying not to spoil) because it was insta-death and there seemed to be nothing else to do. That can definitely be annoyance with old games of this nature, though it also has a certain charm to it, in that you really had to do some trial and error to get through them.
