6 h6 ignoring the point of bg5, actually encouraging white to make a good move (bxf6), which funnily he didn't do.
7..ng6 retreating without being forced to.
9..bd7 not noticing the na4 is trapped, or noticing it is but attacking it the wrong way.
11..bxa4 i don't understand the logic of this considering the previous move is bb4+. if you wanted to take on a4, you could have taken on the previous move without giving white the option of bxb4 here.
22..rxd7 ignoring white's threat, and consequently losing the queen
after this black is probably lost no matter what, there are some tricks he could have done to get back in the game a bit later, but i'll stop here.
you played bad, but the other guy can't exploit that as he's not good either.
there are some good aspects of your play, like the regard for king safety, and trying to eliminate enemy pieces inside your territory.
but overall it seems you ignore your opponent's threats and focus on your own ideas, and also you either ignore or don't see basic tactics leading to win of material for yourself. (na4 can be won with b7-b5).
you should solve a lot of simple tactics puzzles daily without skipping. it would give you the most returns for your effort. but only if you want to seriously improve.
that's my take.
I want someone to say how I played because it felt cool playing this match
