can u sort out my mistakes in this short but a very intresting game.pls pls tell me the wrong move i played and best substitute to that move

Move 4, the main line is Ng5 putting pressure on the f pawn and threating a capture of the rook. I wouldn't really call your move a mistake but maybe you might want to look into that opening if you play the moves e4 Nf3 Bc4.

Who was white and who was black?

I don't agree with 16.g3 opening the kingside. You had a pawn minority there and Black was in a position to counter-attack your pawns. 16.Bd2 is better connecting the rooks an developing a piece while Black is still busy tring to coordinate himself. It also wasn't a good idea to place all your pawn on dark squares as they only decreased the scope of your bishop. 

8.h3 was to conservative 8.d4 exd4 9.Bxc6+ bxc6 10.Qxd4  0-0  11.0-0 c5.  gives you an equal position. At this point 8...Bg4 is to threating since your bishop covers the knight.

I agree with Tr4. At move 4, sending your knight to g5 would have set a completely different tone to your match. Even though the match went 42 moves, I thought you lost initiative at the end of move 6.

Interesting game anyway.

My annotation:

your biggest problem I found besides any specific move (though I do think h3 was a mistake) is that you took far too long to develop your bishop and your rook. they basically sat passively until you were already under a serious attack (caused by you ppening up your pawn structure too much too quickly) then it was too little too late for their development to save you.

i am white

Why not move 13 Bxh6?  to further increase the pressure?
