Interesting...
Personally, I found most of the motions and actions to be rushed, as if you're trying to race through the plot. It's a good idea to allow time for the characters to interact with each other and build up atmosphere.
The only thing that really bugged me was the ugly grey pixels on the outside of Goomba and the zombie paratroopas. Taking the couple hours or so to clean the art would go a long way to make it better.
Neatly done, otherwise. Hope to see part two when it releases.
