Thing is they should try to have people work together. If your solo you have to rely on natural healing (by being energized and hydrated)

The jump attack needs a better hitbox since if you stay still they simply fly right through you. The zombies have a nice speed but to constantly run at said speed is anoying, i say give them stamina, lower speed being something probably a little faster then the old speed.

From reading some of the comments i see that some people don't realize having an axe in your hand is required to open canned food (if u have nothing else). Also that making the hunger and thirst status disappear only means you are satisfied for now. As in there is a good status u can get called energized (from eating a lot) and hydrated (drinking a lot). With both maxed you can easily go from town to town without eating or drinking.(also having them maxed heals you over time, apparently you spawn slightly damage since it says healthy when your full hp). With both maxed you can just drink the plentiful sodas in the world to keep it that way.
