Theme: this is a great fit! You're discovering the world and how best to follow the guides you see.
Fun: awesome! I loved exploring and learning as I went. It was a little short, but that means it didn't overstay its welcome and it was really polished. Might be cool to see a longer version of this some time.
Controls: relatively easy to pick up, and worked smoothly. Nice!
Graphics: I love seeing all the different visual features of the world, and I liked the abstract feel. Would have been nice to see a little more in the world. Visuals that we could use as landmarks would be especially nice since sometimes it took me a long time to realize I was going in circles. But maybe that would make things too easy lol.
Audio: great! I loved all the little SFX touches. I almost wonder whether it would be possible to make something like this as an audio-only game, but that would take more time than you have in GWJ.
Originality: not something I see often. It's like an abstract, opaque (but not too opaque) scavenger hunt.
By the way, does that slider with the eye icon (next to the audio slider) do anything? Seems like you maybe didn't get around to implementing it, which is fine, but I wasn't sure if I was missing something.
