Greek Gift Sacrifice!!

This is the first (as I can recall) Greek Gift Sacrifice I've ever done!! Months ago, I tried doing one which doesn't actually work, but due to the opponent's bad play, I still managed to checkmate with the strategy. This is one of my favorite games I've played.

I decided to play an unrated game (because I'm too scared to play rated because I don't want to lose rating) and did the King's Pawn Opening (which usually I hate). I have read some of @Vitualis's quick wins in his book and wanted to put them to the test. But... the opponent didn't play the way I wanted them to play, so I just kind of do the usual development.

After the game, the opponent accused me of cheating (probably because my rating was around 1270 and he/she is about 1400). Because of the bishop brilliant, my opponent resigned XD!! I didn't cheat in case you're wondering... .__.

Welp, here's the game:
