Pendulous Time and medal in bonus playground
Choose the bonus playground (“B” at the level selection screen). To find the exit, attach to every anchor in the playground and touch at least one of the bumpers. The message “You’re at the top of your game, Operator” will appear. Return to the top, and the pipe will retract and show the exit.
