Hi! Thank you for your feedback.
I'm glad you liked the previous path being shown. It's a case of bug turned feature :D
As for the sound effects, it's been mostly us doing our best yelps in front of a microphone followed by some light Audacity :D
Finally, when you refer to missing ambience, did you play the web version? We noticed it has some trouble loading sounds in some browsers. There should be some (very basic and generic) cave ambience, or did you hear it and are specifically talking about music?
