You have to sign a non-disclosure agreement, so I can't say much about it, other than it reminded me a little of one of the very few modern computer games I've played, "Myst". There were lots of red herrings and false paths to follow, more than I would have expected.
If you enjoy problem-solving, you might enjoy this; if you enjoy computer games (I don't, particularly), probably even more. Only about 20% of all teams competing manage to escape. We got out with about 1 minute and 50 seconds to spare. Everybody contributed significantly to the solution; we would not have gotten out if any one of us had not been there, but we also had a bit of luck.
This was a lot of fun, and our team size of four was close to optimal. Fewer, and you just don't have enough bodies to follow all the possible routes. Larger, and the number of people make it hard to coordinate and put together disparate clues.
If I had one suggestion to the owners, it would be to discard the very chintzy little reward you get for solving the puzzle, and replace it with something like a $5 gift card good for one of their alternate adventures.
