It was longer than expected (2hours), the fact that the puzzles and the solution are on the same card make the game more fluid. Some puzzles can be solved in different ways. It was a little too obvious at time.
I was used to the Unlock! series of games, so this is my first play of an Escape Room type game that is completely non-digital. I was a bit confused about the "resolve in any sequence" sections, but overall an enjoyable game. I played solo, not sure how the experience will change with group play.
