Honestly, when I go back to it after the jam is over, I'm thinking about redoing the maze to add some different sections that have a visual difference to them so that the player can at least tell the difference between hallways and maybe add landmarks to create familiarity. It might help with navigating and realizing you wandered into an area with no exit because you already explored it.
As for your audio, it's understandable if your audio was turned down. I think adding volume sliders in an options menu would help greatly to avoid things like this. I've got a couple other ideas I am tossing around my head too so we'll see!
