I like the idea and design
I got caught in long corridors a lot. Either a hunter or two listeners from both sides. If I echo to see them they will hear me too and head my way. If I'm lucky I can hide, but then there is no way of telling where the enemies are. If you echo again all the enemies will return to you. Headphones (with spacial sound) provide little help.
I can hear the footsteps when they are close, but when the path forward is practicly a long bending corridor with some places to hide it is cruicial to know on which side of the path the emenies are
