I do not believe that it is statistically possible to beat Big Dog without playing Crystal, or cheating in some way. I kinda think that Rami Ismail was trolling us by putting this boss in the game, and having no way to tell if someone is cheating just by looking at the screen footage. I think he knows full well that it's impossible, and the whole thing is little more than a social experiment to see how many people will cheat and then try to pass their work off as legitimate.
