Average in my opinion
Don't get me wrong, the Madness series is a good one... save for that it's kind of like just a rehash. All it does is repeat itself. Not to say that killing scrubs left and right isn't entertaining, it is, but when you've seen it done plenty of times before it just loses it's magic.
If the Madness series is going to go on, I would like to see a little change to the formula... Like... maybe new characters at least?
Also, i gave a low score on the music. I just didn't like that kind of music. I believe that music in a flash cartoon should blend well with the animation and action going on screen. The music is like a sea of beats, kind of sounds like it has something to do with a circus gone wrong, and doesn't really fit in well with the action and senseless murder.
