White made a lot of wasteful moves in this game. Black's attack was rather impressive, although I am inclined to believe that the attack would not have been so successful if White hadn't wasted so many turns. For example, if 52. Rxb3 Rxb3 53. Qxb3 Qxb3 54. Kxb3 then White could have run his A pawn for a new queen without having to worry too much about Black's pawns. And before that, what the hell was White planning to do when 25. Qc3?, 36. Rb3?, 42. d8=Q??, etc. Those moves are questionable at best. The following are examples of how I think the game could have turned.

52. Rxb3 falls to Be7+ (rook is not controlling the rank anymore)

on the second analysis board, 42. ...Qh3 is mistake. Rg3+ is called for (queen is needed on the h1-a8 diagonal to keep the net closed on the White king. Qh3 takes away a future Qe4 which reels the king in.
