Nice job done here.
End of the world based around zombies is no original concept but you took the old idea and made something new and original out of it.
Sure the graphics aren't the best I've seen but they are good, and with quality of the voice acting, animation, and narative, I couldn't care less about the graphics, not to mention how well you've put together all the scenery, beautiful blue skies and green fields right next to grey cities. all seems kinda real. This is a good thing to have on Newgrounds especially considering how rare such plots are. Not only is this original but it's also pretty realistic; School would most likely stay on if there was a big disaster.
I look forward to seeing the rest of the series. And the only target I have for you is to keep up the good work.
