The amount of people was a tad unexpected, and threw off the original plan/reason for the location. This also caused and issue of the letters being backwards, in the future the location will be changed to better accommodate this.
As for the hints they were made to start off easy, and end harder, which I think it did as the last few words took longer for people to guess.
Reminder this was the first time the event was run so it is something that hopefully improve and return again in the future
