Staggered Pawn Wall!?

Well, this was a rather cool game, and as such, I feel it's warranted to post it for my first game for public viewing.  I've never had an opportunity to make a pawn wall, but figured I would try it.  Granted, my opponent could've taken it a different way at any time, but once I cracked open the line, I think it was just execution at that point.  Enjoy...

A taxing game, no doubt, but fun to play through. The one thing I don't understand is why they didn't try to do the same by sacrifing a knight to break down the wall. My king was a dead duck if they would've.
