Maybe this is by design, but it felt pretty impossible to defend the camp at first, trying to keep the npcs alive with the size of it and how they wander off, (I think stepping on a downed zombie also kills you, which got me a few times, that or they were just spawning on top of me) eventually I just ignored the camp and went exploring which led to clearing the game, so that was neat!
Overall it was charming and quite fun, well done!
