Nice effort! The convergence on f7 is only referred to as the Fried Liver Attack after 1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 (the two Knight's Defense to the Giuoco Piano) and now... 4.Ng5 the Fried Liver Attack.
my first youtube analysis

It is usually best to break those pins so they can't put PP on the PP and that is why 0-0 was better than d6.

By capturing on e4 with a pawn White breaks his own pin and now Bxg5! wins a piece. White should have recaptured with the Ne4 in order to keep from losing a piece.

Black has a technical win after she wins the piece on g5 and enters a late middlegame with an extra bishop. The problem with Bg4 instead of Bd7 is that with Qg3 White pins the bishop to the black queen. Black must break the pin immediately or protect her queen so that she doesn't lose her extra piece. She is still technically winning if she does this.

h6 was great because it protected the queen and gave the king an escape square from any bank rank mates. Both players missed the chance to put PP on the PP and to not allow PP on the PP respectively for many moves!

missing the bishop retreating move or recapture is a very common occurrence for beginners. The focus is forward march and attack! Had she seen it, she would have won a whole rook! Practice looking for these type moves.

At the end when the computer suggested taking the rook with the queen it was probably due to a forced checkmate or loss of the queen if he doesn't. After Qg1, she plays the crushing Rc2 winning the queen by forcing the king to leave the defense of the queen.
