This is a really neat idea, though it was very difficult. Even with the extra help, I still couldn’t get past the area with the timer. I found one button in that area but then I couldn’t find the next, or whatever else I was supposed to do.
Especially given your description of escaping a lab after being blinded, I wonder if it would help if we got to experience the area before being blinded, so that there was a bit more of a frame of reference.
Still, this is something I think will probably stick with me due to it’s unique way of expressing blindness.
Nice work!
