First of all, Congratulations! Everyone plays the Amsterdam Catacombs at their own risk. The game can be very intense due to its scary nature and it requires you to be able to kneel or crawl. Additionally you might not be able to sit down for around 100 minutes. We believe that you know best what you are capable of, so we let you decide but we encourage you to not take unnecessary risks. Please contact us if you have more questions.
