Analyze this

Help me analyze this game,please!

I play as white and have the initiativ of the stronger pieces,surely because of the poor development by my opponent, but the game seemed won for me from the begining to the end. And somehow we manage to play as long as 27 moves before the mate. I would appreciate the comments on the game and possible theory info on the opening.

I hope you take time to response.

Thanks in advance.
