Not bad! Although personally I'd have loved maybe some extra dialogue here and there. Also, the idea of adding extra dialogue to a self aware program under a time limit was a nice touch but it's a little sad that since it is only an online version that we can't do that, perhaps that's part of the point. I think while retaining it's simplicity it could definetly be possible to add more depth to the narrator.
While the spelling errors might have been a narrative element on it's own (since they are referenced in game and made fun of it just kind of made the narrator feel a lot less "real" in a sense where I'd feel sad to have them disapear. )
I think if you ever want to flesh this out further starting with creating a more likeable/relatable narrator might be key. You have a great theme, don't feel afraid to lean into it more.
