Developed by Guy Cotten, a French outdoor / safety equipment company, this little browser game called 'Sortie En Mer' shows you the realities of what it's like drowning at sea. You simply have to keep scrolling continuously to stay above the water, all whilst the waves bash over your head. Be warned - it gets a bit graphic in places and if you're prone to panic attacks, this might not be the best option. You've been warned.
