Well, you dropped your knight on move 11, a pawn on move 13, a pawn on move 16, which all kind of led to losing another pawn and knight -- I stopped looking at that point. Its not worth talking strategy or positional chess until you can cut down on your blunders. As far as the beginner principles, you developed fast and castled quickly, so nothing that really needs mentioning there as well. Bottom line: practice tactics somewhere (chesstempo.com is a good place).
You had a chance on move 62: Kd7. Then there is c6+ Kc7 Kc5 Kc8 Kd6 Kd8 c7+ Kc8 Kc6.
62.c5 was a blunder from White. White was winning until he/she played this move, which made the position a draw.
That's my comment but the king go to b6 instead of d6.
Kd5 wasn't a blunder.
Thanks for the comments guys! What I'm getting from this is to practice a lot of tactics and work a bit on endgame. Is there anything about the opening and midgame that needs working (should I switch to another opening, for example) or should I just focus on cutting out blunders for now?
You played 3...Bh6. Why? 3...Bg7 would probably be better
You played 8...b5, creating a backward pawn on a6. (although white's next move, 9.b4, reverts it because a pawn wouldn't be able to go to b4 after that)
You can learn from not only your mistakes, but also your opponent's mistakes.
Your opponent castles queenside on move 10, but one of the pawns is missing. This can be a weakness for the king.
