Big improvement
You did a lot better this time around. There was some fluid movements, it got better as it got closer to the end. There were still some flaws that are common with madness tributes.
Your primary issue is you need more movement, especially at the beginning, the protagonist would stand around and kill everyone then hop around to move. Some easy ways to add more depth in movement is tween the body piece and animate the stuff with the body tweened, then after, animate the feet frame by frame. It makes the movement smooth and even if you aren't good at the feet animations, the smooth tweens make the feet less noticable. If you can get some guides on your tweens you can make a very realistic movement. If you think you can do it without tweening you can make more complex movements, but unless you are really patient and constantly scrub the scene, you can easily make movements too rapid or choppy. I don't know, play around with it.
One other thing is, since you are new to flash, you undoubtly get better as you animate, which normally makes the beginning of a flash lower quality than the end, so it is sometimes useful if using scenes to animate the first scene later on to get a more impressive start enticing people to watch the whole movie.
Good job.
