Quite unsettling!
I initially thought that the things I chose to watch would affect what's shown next, but I couldn't pick up on a pattern, and things quickly spiralled from there, ha
You can like and dislike (or both at the same time) and subscribe, but I'm not sure whether that did anything (or at least, I couldn't figure out what affect it has, if any).
The scrubbing was kind of interesting, though I wonder if it should be impossible to see the correct frame via normal playing of the video; I could see whereabouts it was in each video, and thus it was less about looking for it and more about just picking the right frame from the handful I knew contained it. Though I suppose looking for it during play requires you to pay attention anyway.
The unravelling towards the end was unsettling and the sound definitely reinforced that feeling!
