Lovely flight simulator, I thoroughly enjoyed bathing in the air while rehearsing my flight dynamics!
It's sorta like flying a balloon, only much more agile than real balloons so I suspect the character uses some propulsion devices (or in the case if the character uses own media for propulsion, they might have a reinflation device to replenish used media). It might be worth poking this in future updates as either device will have more fun controls affecting gameplay.
