A very fun and well-made case in 4 stages. A lot of those "aha" moments. I played it on my own which took about 7h. I bet it's less difficult with more people, but I think it still is one you have to spend some extra time on, which I prefer! The "aha" after some minor frustration is much better than not having stroked your beard while thinking hard. Recommend highly! So fun and comprehensible!
