I'm glad I could help ^^
Players always grow tired during the long game. ^^
Let's see...
For the first game...:
The black was doing well until
28. ... Kd7
I couldn't see any point moving the king out of his fortress. I think it was a waste move, and made the king vulnerable. Moving the black knight to threaten the pawn and the rock would be a better move (28. ... Nd5).
20. ... Bc5
That was a very good move. The black side could checkmate the white in 2 turns (21. Kh1 Qf1 22. Qg1 Qxg1) , but he wasted that opportunity (21. Kh1 Qg4).
9. f3
Moving the pawn to block the bishop was a quite risky move. It opened the black diagonal, making the king vulnerable when castled, giving the black bishop the chance to check the white king (21. ... Bc5), forcing it to move because the rock was the only piece that could block it (22. Kh1).
It would be better to castle (9. O-O), or to move the queen's pawn to release the other bishop (9. d3/4).

This is where the turning point happened. The white side decided to go defensive by using a knight to block the black queen, giving the black side time to build up his assault.
For the 2nd game...:
7.Nd5
Using the knight to block the queen is okay, but it would be better to exchange queens, forcing the black king to take the white queen, removing the chance to castle (7. Qxd8 Kxd8).
8. Bb5 c6
Be careful. A wall of pawns sometimes can be deadly.
9. Be2
Noooooo!!! White shouldn't have retreated the bishop yet. Use the knight to take a knight to check the king first, and then retreat the bishop. >__<
