You know, that started out so innocent, spun into something eerily demented, and then finished off with a nice, playful laugh with the kick to the nuts. There are elements of this that I like, such as the concept and the music. The graphics aren't too bad, but I feel like there needs to be a bit more substance, like a setting, or maybe a reason why The Strange Man became the way he is. That seems like a good idea for a next flash.
Overall, this isn't too bad at all. I feel like maybe if you give your character some development, this could possibly develop into a series. I honestly think it has the potential to become something.
