I don't wish to be too harsh on HG titles released during the early days. After all, games were free and expectations were low at that time. Still, it is hard for me to praise this title.
The writing is rough. The game is broken up into rooms with a lot of parser-like puzzles, but it was hard to figure out what to do simply by reading the descriptions. There is a hint menu for folks who are stuck, but the menu isn't very well-designed and will need a lot of clicking. There is a picture of each room in the game, which looks like some diagram I'd scrawl on my engineering notes back in college, but it just looks awful for an actual game release.
I managed to complete the game once and meet the final person, but failed his 'final' test. Still, at that point, I had no further interest in a replay.
