A unique experience. Good job!

This is quite brilliant. The sound design is very strong and the central idea is extremely novel.

I must say that after a couple of attempts, I found that it was too hard for me to seriously attempt... even after studying the map carefully, I didn't feel like I had enough to go on in terms of audio cues. I would be the worst person in the world to depend on in a blackout. :)

That is a really original concept good work! I found it a bit hard getting my bearings though and was not sure what the noise was meant to correspond to on the map so found it hard to navigate. Maybe as an idea you could add controller support and use the vibration function when your close to walls so it could be sound and touch and have it vibrate when pressing against the walls! 

Really awesome idea though :D  

Very interesting concept! I like the idea of an audio only game :)  It was really fun and scary. 

Maybe you could check out my game if you have time?
