I beat this my first time 22-10. I don't know why people seem to be having trouble. The game is simple, and a bit too easy in my opinion. I am not bragging, I simply want to point out that it is highly possible to beat him and was even done on my first attempt.
As for actual game play, it's fun for something put together in such a short amount of time. Simple controls and smooth frame rate make for a thoroughly enjoyable two or so minutes of play. I enjoyed the humorous article that comes at the end of the match as well.
If you ever wanted you could probably expand this into a multi-player browser(or just flash) game that could occupy plenty of the users time. It reminds me of the simplistic but enjoyable SuperFighters game, and while that game is far more developed and I find myself continuing to play it- I feel that this game could be expanded into a similarly enjoyable and long term game.
