Programmed to fail
It appears that if you use the power up for extra points by winning 12 levels you are disabled. When I say that I mean that the program will not allow you to move any of the people. Normally when get over an empty slot it highlights and you can drop your man, but after you have won so many levels when the space highlights you man snaps back to his location. It isn’t like you have stretched the rope to far. It occurs even when you’re trying to place it in the space next to him so there is no way it’s stretched to far. You can get extra time as many times as you want but it will not stop until you quit and lose all your power ups
