I like it, but have not gotten a chance to play it yet, as I'm waiting for the print copy and the special dice.
That said, the content of the pdf is quite impressive. It hits a nice sweet spot between the gonzo nature of Gamma World and the grimmer setting of Aftermath, with a relatively light system and a nice focus on the setting, with the characters expected to become involved in their environments and strive for survival and progress.
The art is perfect for the setting and the production quality is high, with a clean layout and everything presented in an intuitive and easy-to-comprehend fashion.
I can't wait to run it.
