Awesome dude!
Pros:
-Excellent graphic style, especially with the variety of zombies and survivors
-Great Sounds
-Pretty smooth
-Interesting daytime aspect, I enjoyed the risk of losing party members looking for weapons or new survivors
-Easy to learn
-Fun, simple, bloody game
Cons:
-Too easy
-Some weapons worthless or too powerful
Suggestions:
-More personalization of survivors to create a sense of "community" and "bonding"
-Give some survivors names, basic stats and weapon type they are proficient with and the ability to arm them
-Keep the pistol at infinite ammo but for all other weapons, I suggest that players must go out and search for new ammo (Could make this a "hardcore" mode), replace looking for weapons to weapons/ammo, after all one of the aspects of zombie themes is the draining ammo supply
-Traps might be cool
Final Word:
-Keep up the good work
-Whatever you make next, take however much time and effort you need, it clearly shows.
