Thanks, I really appreciate the feedback! I wanted to keep the bleep simple since clarity is so important, especially for blind players. I did experiment a bit with other sounds, like a sonar-style blip. One thing I didn't get round to doing was giving each of the four enemies their own distinct sound which could have added more variety.
I really like your idea about enemies making movement sounds. Id love to explore giving more sound options in a future update maybe rustles or buzzing and others
