Two to four teams of worms on a page torn out of a notebook. Take turns walking, aiming and firing: pencil rockets the wind pushes, ink bombs that bounce, a staple gun, a punch, a huge eraser, a paper plane and a paperclip hook to swing on.
Every blast bites a hole in the page. On the Crumbly page, anything that loses its support comes loose, falls, and hurts whoever it lands on.
Play on one phone passed round the table, against the computer, or with friends on their own phones. The dark page swaps the ink for lava.
