good but feels lacking somehow
I'm not sure about this movie to be honest, but it's at least a 3 out of 5 though so you don't need to worry about that XD I lol'd at the killing spree since I think it's one of the few times I've seen a flash movie with a killing spree with a clear motivation behind it, rather then just for the sake of it ( while we're on the subject WHY is blockhead considered funny? He just strings random words together most of the time).
It was a good story idea, but something about it just didn't work, maybe the animation needed more detail or more work on the script or something. All in all stick with this kind of style, keep doing your best and I guess improvements are bound to happen in time.
