This is by far the most interesting and experimental game in the jam :O The sound desing is really important for this kind of games and i think you nailed it :D
You should definetly add subtitles to make the game more accesiable that way everyone can enjoy it.
Also maybe giving the player an empty map that they can fill would be great :D
Overall it was a fun and diffrent experience i hope you work on this well done :D
