You should track at what times the people click next.
Your like button is too far away from the next button, and neither has keyboard shortcuts.

Site looks great, by the way. One thing I'll say is that I ran into the same reel after just two clicks -- this should be pretty easy to avoid, either by shuffling an array of reels (rather than pulling one out at random), or by tracking which reels I've seen in a session variable.
Good luck!
