Why was my move not flagged as a blunder?

In this recent game of mine I believe my 33rd move of g5 was a blunder but the engine doesn't seem to think so.

If White were to play 34. e5 (which fortunately for me, White did not) it seems to me that White would have an unstoppable passed pawn no matter what Black does.

Any ideas as to what I am missing here? I would greatly appreciate help on this.

Luckily after 34. e5, you still have the winning move 34...Kc6. 35. exf6 Kd7 and you stop the pawns and still have the outside passed pawn

Thanks! I have only begun to study endgames.

I am glad 34. e5 wasn't played. If I had this much trouble figuring it out after the fact, the chances that I would have been able to during the game are not great.

if white plays e5 you also queen by gxh4, or just g4. If he goes e6 then you can catch his pawn with your king so he cant queen with check. I dont think e5 is a problem for you.
