This is an excellent well written play at home puzzle hunt. The puzzles are interesting and fun and would highly recommend it to any keen puzzlers.
We have quite an experienced group and it took as 3.5 hours (taking hints on 1 puzzle and in 1 sitting - though doesn't have to be done all at once). I would say this is much more difficult than your average escape room puzzles - which I think is great given the play at home nature we prefer a challenge (no time pressure). For those less experienced their are hints available.
Another great experience from Mind Maze Oxford.
