I think a very good improvement would be to have a marathon extra to all levels... with no restrictions and an extra star every 5 levels Epic game though, 10/5
Ok, I got a few things. First, they call it a bokken, not a wooden sword. Next, it's a katana, not a metal sword. Other than that, it's THE best game for this style, 200/5!
Ok, I noticed that there are a lot of confusing things about Dr Brukenhemo (Is that right?). Basicly, he'l turn up and you let him in. Then when he asks for an assistant you give it to him. You will be asked to approach a Horde and you do that. Later, ( A LOT Later!) the laboratory will be overrun and the two will die. Reclaim it and keep his research going. Turns out, he found a cure for zombieism. You win!!!!!!!!!!!!!!!
For rebuild 3, could you have monuments ( eg, the empire state building- 20 housing, statue of liberty- + 5 happiness every time. Also, could you have a sort of storyline? I mean, maybe have a leader who was like the man who created the virus? Otherwise, awesome game, 5/5
