It's nice to see that you guys take criticism seriously, it's nice to know your ideas are actually being implemented, instead of going to waste.
The new weapons look pretty cool, but I have to point out that the kitchen knife doesn't really look like a kitchen knife, as the handle is very centered to the blade, a normal kitchen knife, or at least the ones I'm used to, has the handle more on the back.
Further, thank you for explaining the World Beyond to me, a few suggestion I have would be the Wastelands or something generic like Infected Area.
I like the idea of having several towns, the coolest thing about it would be that you can actually visit other towns, I really like the idea of raiding other villages and I'm pushing you to implement that.
Another thing that would be cool is a multi-player mode. Killing zombies on your own is of course fun, but doing it with friends would of course be even more awesome. I do understand though that you don't just implement a thing like that, as it takes time and effort, but I think it should definitely be something for on the to-do list.
Also, I just noticed that the side-view has a pretty oval head, I recommend making it more circular, otherwise it'd be very chibi on the front view and suddenly more realistic on the side.
On the zombies, I think they should have a more zombie fitting pose, with the arms up front, at the moment, they seem very lively. More sprites would be cool too, at the moment, you have a naked zombie and a zombie with clothes, I think there should be more variation there, zombies with just ripped shirts, zombies wearing a hat, you get the drill. Variation can really make a game.
Anyways, I don't have much left to say, it'd be nice to have some play-able version, or you should at least get beta-testers as different perspectives on things can really help.
