I love it :D Feels like a blend between Myst and The Witness. I got stuck in some places or got to later areas without completing earlier first, but in the end figured it out. The closing your eyes mechanic is great, really liked the part where you have to estimate the walking time to not fall off. Would've liked to maybe enhance the hearing sense when closing your eyes? It feels counter-intuitive that the sounds would be so strongly muted. Overall great job!
