This has a lot potential to be really interesting! That being said, I wish the sounds around you helped your sonar ability similar to how the rave trio in the park is "lit" up. I found it really easy to get disoriented like frustratingly so. The vocal cues seem to stop after you get your keys. Then when you get outside its just non-stop beeping. I want to play this game but i feel like its fighting me. Maybe if the sonar was slightly better and gave you a longer time to scan around you, and if your character kept prompting you what to do next.
It does feel over-scoped for this 48 hr jam but what you did with the environment is great and when you do have visuals of that environment it looks really cool. The environments sound design was very well executed (except the beeping...) . The start screen was also top notch.
