Help with my game

Hi !
Here is a recent game i played. It's a 20 min game, i'm around 1500 rated.

I was really liking my position but it seems like it was bad. I ended up blundering but the position was bad anyway.
I made some comments tring to explain my reasoning.

Can someone explains where did i go wrong and why ?

Thank you.

I would recommend watching some of Daniel Naroditsky. He puts out great instructional chess content about every other day. My own advice would be to focus more on developing your pieces and getting your king to safety before making pawn pushes like a4.

you should castle before

24. axb6 is horrific. You know Black Queen snaps back and you get nothing from it because their pawns aren't passed anyway. Then Blacks Queens stops you castling. By missing the opportunity to castle, that leads to the downswing in the game. And you can't develop your Rook now.

Morale of story is ignore swapping pawns for no reason and just develop.

Rest wasn't too bad.

@Aelyann According to your annotations you seem to have a solid positional understanding just work 1 hour on tactics everyday for 1-2 mounths think nicely don't look to solve many puzzles but all puzzles correct soon you will see a drastic change in your chess
