Addendum: I just reached the end, or so I think I have. This impresses me. The use of the ever-familiar YouTube (or other video-website) experience and making a game out of it, the interactivity itself, the progression, the visuals, even capturing the atmosphere and the characterization of the website itself. All this in itself makes for an interesting experience.
Then there is the ending video. I like the sci-fi premise. I also like that this ending cements what seemed to have been hinted at throughout most of the game: That this is a commentary on the addictiveness of singular websites, video-based in particular, and how it can affect our judgement. This angle deserves respect.
