Y'know...I was a little disappointed that it wasn't an actual game. It looked like it could have been pretty entertaining.
The animation was pretty solid, and the audio appropriate, but a few times while speeding along you come across two identical zombies side-by-side. I can understand not wanting to animate so many different zombies, but maybe they should've been spaced differently?
I also thought it was a little entertaining that you can proceed forever until you build up enough speed...so you have this suburban-commando-type being all gritty while moving maybe a kilometer an hour on a segway to approach the zombie horde. Brings a particular Monty Python scene to mind.
