Like others have mentioned - it took a while to load. You definitely get major points for having a 'sandbox' portion that you can move / interact with before you play. I played a couple of times, trying to figure out how to 'trap' the zombies in - only to be delighted when they started smashing the walls! I also like the hunger mechanic - forcing the player to move is good game design. Things that could be improved on are mere 'polish' elements, like better sound, better hit determination and the animations look like they could be a little off. Still, a damn fine job!
