Well, we failed. We attempted Farewell and couldn't find the heirloom.
This was my first time in an escape room so I have no idea how this compares to other escape room. We had a group of 7 (Four adults, two teens, one child). There were a number of puzzles to solve. We unlocked all except the last two. I would guess we would have needed another 20 minutes to solve them. All of them a solvable for sure, but only with the clues. Without the clues given on the screen in the room, we would have been there for days.
The staff was friendly. The place is easy to find. If you are into escape rooms, I think this one is worth a try.
