I enjoyed learning about the Dead Zones! thanks for taking part, it sounds like it was a stressful one for you! Tell your son the art was cool!
It felt good and atmospheric, despite knowing that there wasn't anything to find down there, my curiosity was still piqued with the limited vision and the general atmosphere. I did feel the Iron Lung inspiration, which a good thing! Controls felt good, just got to a point when I started crashing the sub that it felt like it was hard to recover if I was up against a bunch of terrain. Also just tapping tab to stabilise would send me spinning sometimes (where as holding it worked as intended!)
