Constructive critisim comming at ya.
I waited there for a second looking at a white box wondering what was 6.7 and had no visible preloader. Then it popped up right when I was about to give up on waiting. Preloaders are a must! When your file size is that big it can be one of the biggest make-or-break points of your flash. You don't want to keep your audience waiting wondering what is going on.
The idea is unoriginal, I don't know the countless madness dress up games that I've seen in my years here at NG. They all tend to look the same, the only thing that changes is the detail in the artwork. Even then, with madness characters you can only do so much due to the lacking nature of detail in the original madness characters.
You are very good at drawing these madness characters and weapons, and you are not a bad animator in the least. Your coding skills look decent, and I would like to see your artwork move to something more original. You should be designing things that people will want to duplicate, not the other way around. :D
Good luck in the future, I hope to see your improvements!
