Good.
A BIG improvement from the first one.
However, you say that you really worked hard on it, but it seems to be made very lazily.
1. Most of the backrounds were simple
2. Many of the kills were offscreen
3. Guns can't go through flesh by lightly throwing them at someone, and if they could, they wouldn't make the same splatter sound everytime.
4.Characters remained stiff as a log.
However, I loved the humour, the violence, and the movements were very good.
Hopefully in number three you will overcome these problems and it will rock even harder than this!
