There are not that many 4 Player , coop Puzzle games and this one is not only rare it is also great. The team has to suss things out together because every movement might affect one of your teammates. Blocks have to move in lockstep to shield one another. A button pressed might have consequences on other blocks. All player moves might have an effect on other players. So no one is ever done with “his part” since they might reach their final position with ease but they have to enable another player somehow to do so as well. The gameplay mechanics are just great since they introduce several modifiers throughout and develop them further. Levels are clustered around a common theme. The act of playing was just great for our group. Everybody looking at the screen, no controllers in hand and discussing, making suggestions, taking hypotheses from others and develop them further or kill them off. A real good communication game where every thought and idea counts and every player contributes to victory. Also the game gave us some chuckles since some moves can seem so reckless and narcissistic. This one is utterly recommended.
