Had a spare half-hour so thought I'd do another game. Here it is. In this one, I go behind fairly early on after some opening mistakes, eventually emerging an exchange and a pawn down. However, I manage to set up a blockade, meaning that White had to sacrifice a little material to break through my defences. The way he chose to do so was incorrect; after some captures, I emerge a pawn up going into the endgame. The endgame is conducted badly by my opponent and I manage to score the full point! Never give up in chess.
