Some ideas from my son
As a bad parent I allow my kids to play games with radiation and zombies. He has these new ideas for the game: - ability to grow in size (think: Guliver's travel, and make it fit the story - should be no problem) - feeding animals (he wants to become friend with both zombies and animals I can hear) - he wants cows, pigs and horse too (basically a farm I guess... If you can put that I between all the zombies that'd be great!) - give weapons to the zombies (that sounds dangerous, I'm not sure it's such a good idea...) Anyways, just put all of this in next update, and he will be real excited and he will tell more people to play the game. Thank you for your consideration
