I love the concept for this game. The voice acting and audio is also really cool. That being said, it's hard to catch everything that they're saying, especially when it's instructions. The game sounds like it has an awesome story that I'd love to know more about, but progression is too challenging for me. It's way too easy to get lost, and once you lose the trail, it's hard to find where to go again.
I would like some sort of visual feedback, even if the character is blind. There are surely ways to represent the world and the level to compliment this theme, rather than undermine it. Great work!
