Ready to take the plunge? Try to climb all the way to the top of the sheet of paper: jump from platform to platform, equip yourself with jetpacks, avoid falling into black holes and blast the bad guys with the balls straight out of the tip of your nose. You will love to see the scores of other players scribbled in the margin as you beat them. But\u2026 beware: once you start, you won't be able to stop!
