A number of aspects of the game point to the presence of air as a surrounding medium, from which it may be possible to deduce the importance of sound to Mario-like beings. Of course, all these points are counterbalanced by the fact that Mario doesn’t usually experience horizontal drag (I think?).
The Koopa Paratroopa has wings which flap as it moves; when they lose their wings, they stop being able to fly.
The fireworks at the end of a world (e.g. world 5-2).
World 2-2 takes place underwater with very different physics that clearly point to a surrounding medium. At the beginning of the level, Mario emits bubbles that rise to the surface, strongly suggesting that there is another fluid above this one; it’s not unreasonable to suggest that Mario contained that fluid, picked up from an earlier level.
