The first few challenges were quite fun, but at challenge 16 now and its just silly. Its all about how lucky you are in your first draw and what your opponent plays. 90% of the time you die round 1 because you don't have a healing card or your opponent starts off with City of Rylaih or some major damage card.
That wass probably the most annoying game I ever played, but it was well made. The author made every effort to make simple running and jumping forward result in death by suitable placement of obstacles leading you into the next trap. 4/5
