What would you have done? I took to long thinking so I lost out on time and didn't make a move .

A few thoughts:

1.) 2. f3?? is a serious blunder which severly hurts your kingside and developement.  The only time I ever play f3 in my opening repertoire is in some variations of the sicilian. (e4 c5)

2.) Even after the blunder, after move 5 you had an excellent position.

3.) 6. g6 is a blunder.  It makes no sense to fianchetto when the diagonal is blocked by your own pawns.

4.) 9. Rf1 was probably better.

5.) 13. Qg1 was a good move, Qf1 might have been even better.

6.) 21. Your rook was probably lost anyways.  Maybe Rb1?

Hope this helps!
