Meeh
You should improve your story, this flash had none. If you just want to have a kill movie you should add more action.
The level design was kinda plain, but then again, that's what madness movies usually look like. (But still the sign saying "in case of fire break the glass" looked bad) Next time try adding some ambience to it.
And you probably shouldn't do madness, it's kinda over used. Try finding your own style ;)
