Beautiful! Top marks all around. I love your approach with this task and your clever placement of the almost crossword like narrative for certain sections. The tutorial is so fluid while also adding to the story. The sfx were not only a perfect choice, but implemented so well. This was polished to a gorgeous shine.
I do wish going down the long slope was a little bit slower, so I could take in the entire narrative there (I did appreciate being able to go back up it ... but this was the one spot where I didn't like being locked into movement - everywhere else it made the experience more fluid, but here once I saw the story I tried to go back only to wait to return to the top). As a whole I think the camera could be zoomed in at least 10 to 15 percent more, but I do like how open the space was and the feeling it gave me, but it made reading more difficult.
This is a small nitpick ... not even a nitpick, because I loved this experience as a whole. But at this point in the game ... I thought I was a genius who was going to back up and fall and discover some secret narrative. I did not, but I'd have given you six stars if I could if that happened.
Really well done. Love it.
