A very interesting game, being blind and relying on sound was definitely an experience, at first I was so confused when I would pass an intersection and the direction it tells me always changes (like telling me to go up and then to go down and so) until I realised it was telling me about all paths of the intersection. It's very frustrating when there's not much to go off of and at first it didn't seem like a game I can complete without feeling frustrated about it, but I eventually got there and it was great.
I basically used the flare very early just to even orient myself, I used this... potion as soon as I got it and heard the flute to my right, after I reached the flute I was left wandering until I heard the sound of water, the Sound Cues were very much a godsend, which is the point, and it's an amazing experience. Great job on the game!
