Update Please!

I would really like to get another update on zombieville. The last update occurred in 2011 and I would like to get some new content. I had some ideas:
1. Make it possible that you could heal your partner if they take damage.
2. Add some grenades. Explosive fun!
3. A 4th weapon upgrade.
4. And whatever else you think would make the game better. Thanks! :)
