I'll start off on a positive, I think this is a really cool idea, as soon as I heard about it I started thinking about how I could run it.
This however is the only good point. The rules are awful and very badly explained with hardly any examples. There is little to no background and what there is is very vague, for example there are rules for electing leaders within the PC's but there is no explanation of how the leadership is enforced by the owners of "The Farm".
If you've read the blurb about this game then you've already got everything of value from it, if you like the basic idea you'll be better off developing it yourself for whatever system you prefer.
I know it's only $3 but all you're getting for this is a half assed set of rules and a basic pitch for an adventure.
