Definitely add the ability maybe to chop down trees and place barriers. Also, perhaps add the ability to collect sand and bags for sandbags.
I found the game interesting, but i got bored as no new zombies appeared other than one real tough one, and Id basically found all of the strcutures. I found the survivor man, the lmg ammo cache, and the army barracks, and i didnt even die. I just quit (granted all of our barriers were gone and my men were almost dead). You need something to make the game interesting. A goal.
For a generic example, the goal in Nazi Zombies initially was to grab the ray guun and a browning and camp till you die. The second one was turn on the power. Didnt really like the third one... The fourth one introduced teleporting, Pack-A-Punch, etc. Your game is kind of bland.
Ill try to suggest something. Lets see...
-After x amount of days you get rescued?
-Youre traveling somewhere, and theres a series of maps?
-You have to gather survivors and resources and get points for them once you die?
Maybe unlockables too. But this is all extraneous stuff. I feel like what you really need is repairable barriers, more types of zombies (fast, slow, invisible, etc), more guns (maybe a shop).
Anyways theres my two cents and then some
