My brother gave the double subscription box to me for Christmas, and my Roommate and I had so much fun solving the puzzles. We spread the three chapters out over a couple of weekends but picking back up where we left off was easy. I’m very impressed by the detail of the puzzles, every inch of the box it came in was used for clues, the combination of the online portion and the physical clues was seamless. All around impressed. Ice Age Park just arrived and I’m very much looking forward to this next challenge.
