What was I thinking? ch. 4

Here is another of my games, played online with a 15 minute clock.

I particularly enjoyed this game, because despite I have pretty much no knowledge on white's opening, I managed to use some concepts from other openings I have reviewed to handle the situation.

I had some assistance from my opponent at the end which led to checkmate, by him going after all my pawns.

I wonder if it was possible for me to win the game with the material at the end, had he seen the mate and escaped...
