If you're going to make such a claim, you need to provide a link.

Peter's tower is currently the world record for tallest tower. Towers that were taller but are no longer up on this site were cheating, hence them no longer being on the leaderboards here.

I'm actually not entirely certain how the old leaderboards worked, but hacking your tower height is notoriously easy to do (try playing WOGCorp in online mode... there's always tons of hackers). It's almost certainly not legit. In any case, it's not submitted to the leaderboard here, so it's unverifiable even if it was.

(Also glance over to the column on the right. The top player there has 311 Goo Balls collected in Going Up. Hacks. )

lol true
