Nice work, and as beautiful as ever. I think it was a good use of the theme to derive movement based on the material sound you walk over. I also had difficulty getting anywhere, made worse by the switch lights going out after a little while :o and didn’t get as much of a story per se (I didn’t get far past stumbling in the dark, so that may be part of it), but still all around great work. Appreciated the subtly of the missing flyer in the wind at the start.
Oh, and I found the “bumping into a wall” sound just a tad too strong/sharp/jarring, minor feedback. It’s hard to balance a symphony of sounds when they are your source of navigation, so I also get that it needed to be clearly recognizable.
