First:
Please do not play this game with the ADRIFT 5 Runner as it will only work properly with the ADRIFT 4 Runner and perhaps with the Scare interpreter included in Multi-interpreters such as Gargoyle etc.
This is a pretty good mystery game where you must find evidence on who is the killer at a party, otherwise you will be the main suspect.
Looking at some reviews, I think this game is a bit underrated. Sure, it has a few issues, but nothing critical. The only "puzzle" I didn't like was that I had to:
(decrypt with www.rot13.com) CHG GUR OBBXF BA GUR NCCEBCEVNGR OBBXPNFRF
Before I could do something completely different. That wasn't very logical. Otherwise, puzzles were fair. And the game includes a walkthrough if you get stuck.
The game may require that you have a bit of experience with text adventures, but if you have that, there are no real technical problems. For instance, books couldn't be referred to as a book, e.g. GET BOOK wouldn't work, you would have to type e.g. GET RIGGING BOOK. Not really a problem as you will quickly find more books and you would have to be more specific on which book you want to read anyway. Stuff like this may annoy some, but not me. Also, the game accepted the use of "it" in a few places. However, sometimes using "it" gave a different response than using the noun, which is of course a problem but didn't appear very often (this problem is mostly gone in ADRIFT 5 games if the authors apply specific tasks whenever possible).
Despite these few niggles, it was still quite entertaining.
Decent parser, though a few problems with "it" and books could not be addressed as just "book".
I think the intro and the wandering NPCs set the tone well.
I am not sure if the game can become unwinnable but I don't think so.
Except for one puzzle, I liked them all.
A good game, which deserves to be played despite its age.
