I like this MiSTing even more than the one for Detective, for a couple of reasons. For one thing, the original game needed spoofing because of its extremely primitive design, not for being so laughingly awful like Detective was, and so the emphasis on the MST dialog is on that aspect of the game. Another thing is that this MiSTing has an intermission, which I found to be hilarious.
Playing through the game was actually pretty enjoyable with the heckling that stripped it of any seriousness. The original "game" itself was just an interactive stream-of-consciousness set to an unordered "maze of twisty little passages." I did enjoy the room descriptions with the MST comments added. Just be aware that you'll probably squeeze only about a half-hours' worth of enjoyment from this piece.
