A jigsaw+ puzzle game with dirty, grimy, rather ugly art. The cut is kind of playful and uses impossible in real-life pieces, which sometimes depict something meaningful. It tries to be more "intense" with small arcade zombie-defence mini-game. It's amusing at first, but then just gets irritating.
Bulk of the achievements are awarded for the jigsaw part of the game, the rest is for zombie-hunting and some those are really bad. One asks you to waste a one hour of real time spamming the same button, another to do that until you get 5000 kills. And after that entire hour i still didn't get it, so screw it.
