A great story.
This is definately one of the most creative flashes I have seen. I love the storyline behind it, a city full of missing socks is a hilarious concept. I also like the alternative reasons you included at the preloader. The animation was alright, I thought the sock looked pretty creepy, but I like how you animated using your own style, I respect that. Plus the plot made up for any problems I had at all, this seems like something that would be told in a children's book.
All of the trials the sock was put up against were very unique. I liked the part when he was riding the iron the best. The music was great too, each song fit the part very well. I like how you synchronized the swinging axes with the song too. Plus the sock doing all of the silly dance was enough to get a ten by itself. Overall, not a thing to complain about, a fantastic story backed up by entertaining animation. Keep up the excellet work!
