Interesting bishop-pawn game

Why didn't the game end at move 24 if the black rook takes the white rook? Besides that, it is possible for white to draw if he first moves the bishop to D5. Then Black moves the king to D2. White moves bishop to C4. Black moves King to C2. White moves pawn to A4. Then there is no way for black to threaten white because of the chain of connecting pieces. White can postpone the game indefinitely while black is helpless in ending the game.

Yes, by waiting for the black king to move, taking the pawn on f6, then moving the bishop to a4, and keeping it there.  If black moves his king to force the white king from going back and forth, the bishop can start going back and forth

At the end all black has to do is work his king around to the a2 pawn. His bishop is covering pawn on f2.To Ap16: if white goes a4 black can capture en passant.

No, he didn't miss mate because white has the bishop on g5.  Unless I'm missing something?

I think the final position is a draw because black has advanced f3 which allows stalemate tactics. If blacks pawn would be in f4 instead of f3 the ending would be winning. Therefore 60... f3? is a mistake that looses the win (see variation to move 60).
