Could you lend me a hand? I'm quite hungry..
Entertaining game with great music,though it gets repetive to fast. You could add some kind of mobile obstacle,like soldiers,other zombies or whatever,since that would actually keep you away from the "Eat-everything-that-moves" tactic.
Upgrades would be nice,too. For instance, one could allow you to vomit,killing everything in an area in front of you,whereas others would temporarily turn into a ghost,allowing you to pass through obstacles.
