Awesome!
I kinda like it, but your comments seem kinda generic... and not new. But the flash itself is really good. I like the music, as well as the nice graphics, but there's no sound...
I like the main character, except at the end. He looks a lot worse than in the beginning. Getting lazy? Hehheh. Especially him running...
Twould be nice if you explained how he created the little devil, and why it hates him. Also, he should have made another one, so they could fight. But then it would be even more generic, and yeah.
All in all, a very nice flash. Keep at it!
