Contraption Maker

Contraption Maker

Has there been some changes made to the main menu's background contraption?
I've noticed the basketball is no longer hitting all of the mouse motors on the left side.

Also, there isn't a way to hide the main menu, so I can't see the full contraption that's happening in the background. (The contraption with the blimp at the bottom, and presumably, the goal is to get the baseball in a cardboard box.)
