It wasn't... bad.
But it sure as hell isn't the best flash on this site. It obviously demonstrates effort, but this just isn't up to par with many other flash animations or games of which it has surpassed in score. Overuse of gradient and sketchy animation was a big turnoff and the ugly motion tweens made this reek of an inexperienced project.
Don't get me wrong, I think this obviously had a lot of work put into it but I just can't justify it in the number 1 spot.
I'm absolutely astonished, really.
