How to win against the King's gambit

The king's gambit is a trickie opening, but if you learn to avoid some traps black are up a pawn and if they manage to force some exchanges they should be winning. In this blitz 5+0 game I believe I did a great job, not only keeping the pawn and preventing my opponent from trapping me... but also increasing the advantage and simplifying the position to a completely winning endgame four pawns up with a bishop against a desperate lonely knight... My opponent had a decent accuracy 85.5% while mine was 89.6%. Enjoy the game (more comments inside the diagram):
