Feedback on my game please!!!!!!!!!!!

I beat my friend in this game, but I'd like some feedback on how I did. I'm not a champion player, but I know how to play and I've been getting better every day. Any feedback is appreciated. Thanks for looking!

Interesting game.

When Gangarams played 20. ...Kf8??, you played 21. O-O-O, but you could have played 21. Nc6+ to win the queen.

That would have made it an easier game for you.

I didn't see that checkmate, though. That was great!

When your Queen was pinned at 16. Rxe4, you should have took the rook for a better trade. that ended up fine, but yeah.

Thanks for your input guys! I honestly didn't see that I could have played 21. Nc6+ to get the queen at the time lol

17. Nxf6+ wins a rook I think
