Basically, you're the only human in the world (or at least the town) and all the women are anthropomorphic animals that can eat you. If you're not into vore, there's not a huge amount for you here. Basic gameplay is: Get job so you can pay for food so you don't piss off the deer nurse you're staying with, or else she'll eat you. You can move in with a hippo, but you become a feeder, essentially, and are expected to feed lots of food her relatively constantly or she'll eat you. Other women around town are willing to eat you, if asked or annoyed, and won't let you out if they don't like you enough. You can buy things at the store to potentially save your life, though, from what I've seen, generally they don't help much other than making it take longer to die, if the pred isn't willing to let you out themselves.
Goal: Survive. Make money and build up your stats and relationships so you don't end up being eaten alive. Or don't. That's also an option for those that just want to see the vore.
