I love it. Cute lines. I put the other two main ones that explain why neither
1.Kxg2 nor 1.a4 do the job are below, so if you want to solve it first, don't
scroll down. :-)

[D]8/2pp2pp/8/2PP1P2/1p5k/8/PP4p1/6K1 w - - 0 1
1.a4?? bxa3 2.bxa3 Kg3! (White gets mated now) 3.a4 h5 4.a5 h4 4.a6 h3 5.a7 h2
mate
and
1.Kxg2? Kg5 2.a4 bxa3 3.bxa3 Kf6! (that's why 1.f6 is necessary) 4.a4 Ke7 5.a5
Kd8 6.a6 Kc8 and the Black stops the pawn in time.
Finally, in the main line 1.f6 gxf6 2.Kxg2 Kg4 3.a4 bxa3 4.bxa3 Kf5 5.a4 Ke5
here 6. d6 and 7. c6 are the only way to prevent Black's king from crossing
through c6 to stop the pawn.
