I've been playing some now. A few things I've noticed:
1. There's a lot of menu options which evidently aren't implemented yet. Similarly, there are some other survivors, but they don't do anything except say random stuff when you bump into them. The first would probably be best removed for now, and the second certainly would.
2. Water is really hard to get. I'm constantly raiding for water jugs and juice boxes when I have enough cans and MREs to last my group for well over a week. It sometimes seems that there are more boxes of MREs than bottles of water!
3. Gear is really really easy to get. My two-man, one-woman group (Short Round, the kid, died early on) is all equipped with a katana, a handgun, military armor from head to toe, and padded clothing, and I have a helmet, a wakizashi, six shotguns, seven combat knives, a spare handgun, nine crowbars, four extra katana, seven spare military body armors, eight kevlar vests, an army helmet, and five extra sets of padded clothes which aren't being used. This is around January 20th. They can take out any zombie in a blow or two and are almost unaffected by zombie attacks. In short, the game is now based on finding water and getting the first strike on zombie beasts and knifehands rather than actually surviving like one would in a zombie apocalypse.
4. Zombies gasp in pain, groan in agony, fall unconscious, glare at people, etc. This could just be a quirk of the type of zombie involved, but it still seems wrong.
5. Zombies can get up after headshots, it seems, and seem to go down too easily from body wounds. Again, could go along with the type of zombie.
6. Zombies never appear in proper hordes or even packs, just a zombie or two, maybe three, stumbling towards the group before getting cut down once they enter range.
7. Overall, the game is too easy once you get through the first few weeks. Even the Spectre of Thirst doesn't help--it just means you need to wander through a lot of complex before finding enough water. The only thing that can even injure you is a lucky strike from a Knifehands or something, which is usually only possible if you wait a moment too long when letting it approach.
8. The handguns look like potions. It irks me.
In short, it's a game in alpha and in need of work. Keep up the good work, though, and it has potential.
