Not the best
While a pretty good flash on its own, there's one thing I kept thinking: This is nothing like madness. But I think you've been told that enough so let me tell you how to make it MORE like madness. First, the music shouldn't be hardcore, but more goofy, which adds humor to the killing, rather than just making it a show of blood. Second, on the flip-side, put more blood into it!!! Madness is famous for its extreme decapitational, orrifice-creating antics!! Third, fewer pauses between killings. The cool part of madness is the quick transitions to the next kill. Fourth, don't make the sound effects so damn powerful. Madness is good-hearted violence, so no more bassy gore-pounding sound fx.
Otherwise, keep it up...I see potential in you!!
