Worst blunder of the year contest?

Actually, I can't say it was a bad game but for the awesome blunder I made at the end of the game. So great a mistake, I couldn't help it but laugh at myself while reviewing the game. The score estimator changes from white winning for 20 points to black winning for a wide 80 points margin.

The review showed I could have played a lot better. I've seen certain moves which would have modified the result of the game. The invasion at the top wasn't handled properly and so on... You'll find some of the variations I explored while reviewing on the sgf file. Please, feel free to comment on any white move. Though you may find some laughable moves, wait till movement 226 before

So here is the game:
