I liked the narrative here and how the story reveals itself as you walk. One suggestion, perhaps the 'E' ui button should face the player, because it is very easy to miss them, especially when it doesn't always appear on the same environment object.
Also when I reached the end, I wasn't sure if something was supposed to happen as the game seemed to end a little bit abruptly and it's unclear if the story has concluded.
A minor bug: When you open a note when running, the running sound does not stop.
