This game is nice and soothing and fun for my OCD self. I seem to have a problem getting the zombie worker, though. I've clicked one of each item for each category at the bottom, but nothing happens?
Am I missing something? I have a solution that seems perfectly valid on level 25, but when the ball rolls down the last incline, it smashes. Is there a max speed or something? If so, it should probably be noted in the instructions or tutorial.
