Got a laugh out lf it as art!
Definitely not a game - the only clear distinction for a game is it should have some mechanism to stop the player from progressing to a desired end. Note the player doesn't ever have to make it to this ending! Not interactive - if I poke it it doesn't react, other than progressing forward or maybe revealing a secret. Definitely art, but sadly no "flash art" category. And sadly most flash art (interactive or "flipbook" as is this) suffers for being neither a movie nor a game.
Generally to stop claiming everything as art, art should be concerned with the expression of an idea / ideas - which the this does nicely - except maybe the leap to nails... damn rogue nails always competing with the screws!
Maybe announce it to the world as art, apologise profusely for having to submit it as a game or movie, and tell everyone "Screw you too!"
