Failed on my first try, but the second went great. I think the key is to have a big military so you can keep the zombie population low, and to establish a lab and get zombie-killing research done early.
Excellent game, and probably the only to capture the essence of this aspect of the zombie apocalypse.
Some general tips for new players:
1. Make sure to check on your options for each new building type you come across.
2. There are multiple win conditions: Curing zombism, destroying the source of the zombies, establishing a government, and retaking the entire city
Are there multiple endings or anything? My game ended with Santa framing the Japanese guy's song, but I guess that means the little girl didn't get to see her mom for Christmas :-(
A fun game, but some of the training modes could be a lot better. Running in particular is broken, since you can't jump when hopping and you don't know when the duck will hop. Flying eventually ends on its own, and the obstacles are easy to dodge, so there's nothing there to challenge you
