Very Cool Game, it kind of reminded me of a wack "O" mole from my younger days but much less stressful. The time limit gives the game a bittersweet but final ending that feels right, it matches the somber feeling of autumn.
My only bit of constructive input would be that a way to restart or continue would of been nice. Other then this little naggle this is a Great concept for a game, if its was to be expanded on later it could easily become a four season type game for if the cosy fall jam becomes a seasonal thing ;) "wink wink turtle".
