Graphically, I like a lot of the choices you made, the zombies are very fun, and I can't wait to see them all. I also enjoy the music, however, I do not like the sound that the alerts make - it's a touch grating after the third one. Mechanically, I like the building of the army, the careful selection of troops as you head into a city to figure out the best way to kill the humans. I do not like how slowly revenue builds, nor the limited beginning income - It becomes incredibly difficult to manage funds after only a few days, and the diminishing returns from the Marketing department makes it very difficult to keep a steady cache of zombies for invasion. However, I do like the concept, and can see it going in a really fun direction, were it just a little easier to balance funds.
