Iron Lung is a short, atmospheric game whose degree of fun depends entirely on your ability to navigate blind. You have a perfect GPS and a map and you use them to traverse an area and take photos. If you don’t know how to navigate, you’re going to repeatedly run into the ocean walls and die. If you do know how to navigate, it’s a fairly short and tense experience.
The game does a great job of setting a mood. From the introduction to the gameplay itself and the tiny little details in your cramped space, it’s all building dread. When I got to the end, the word that came first to my mind when trying to describe it was “effective.” Iron Lung is effective at what it is doing.
