Great entry!
I have to admit that I was lost trying to navigate, even though I've read the readme. There was just too much going at the same time for me. This might be just me, though, I'm not used to playing audio-only games.
So sadly, I only got the object in the room where you start, I've managed to get to the storage room, but was lost here as well.
I think you probably did a great job on this, reading the other comments. The combination of wall proximity feedback, a "target" indicator, as well as the white noise for empty space is a good idea in general, and the other features mentioned in the readme are promising as well. I will probably come back to try again later ;)
For me, the one thing I would really like to see is a tutorial or an introductory section - and I totally get that this might have been too much to do during the jam, given how much you've managed to do already.
