I wonder if I am the only one about to suggest changing the alert sound into something less of a jump-scare. Last time I heard it I had my heart nearly stopped. Not only the alert sound was much louder than general ambiance and music, but also very jarring and at maximum volume upfront. I wonder if the effect was aimed at making players wet themselves.

My suggestion: either change it into something less violent or just add a bit of a fade-in to tone the suddenness of the effect down a bit.
