I did actually. It turned out way better than I expected as well. Sadly, I didn't have time to do a dry-run to see exactly how long it would take a group to escape so I decided to go through with the first group to help them along if it seemed like it was going to take too long. The time-limit was 30 minutes...even with my help the first group took over 45.

I ended up getting rid of about half the puzzles after that and went in with every other group to help them along. Even with that no one was able to make it in less than 30 minutes. The closest was 32, so no one was able to claim any of the prizes I had made up for them.  But, we all had a great time and I would love to do it again. It was kind of spur-of-the-moment this time so I wasn't as prepared as I should have been, but next time I hope to do things right. I'll be sure to hit you up for advice as well. 

You can make a legit business out of it eh. Many do. If it's something that interests you!
