The only effective way to pause is to build up two walls of bodies around you, and get a kind of roof. Then jump. You will glitch, get stuck, be unable to move, but you can use PSY. When you want to continue, keep killing people until you get forced back to the top
That's weird... I started up the game, and when i got to the menu, none of the buttons would work. I refreshed the page, and I instantly got the easy badge. Of course, it works now :)
