I love it. It reminds me of a 2.5D pixel-graphic version of S.T.A.L.K.E.R. With a story and more to explore, I would love to play this.
I was mobbed by wolves right away the first few attempts. It's got good controls for keyboard and mouse (please keep this option) and it's easy to learn what to do.
I also tried it with my Logitech Gamepad F310 controller, and it worked perfectly. I am not a fan of controllers in general though, so I think I would prefer mouse and keyboard.
I can see it being fun with coop too...
