Personally, one of the easier 4P minigames in MPDS.
The aim of this minigame is to jump to the top of the clock's interior, using gears and platforms to get there. The game suggests avoiding the paths of others, but I beg to differ in some cases.
The worst part of this minigame was when you jumped on someone and continued bouncing on them until their next move. But that's also a great springboard to a just unreachable platform =P
I own all levels of the comps, and I usually take the left route all the way.
