I take advantage of the autosave right before the Dizzy underground installations, and I always wonder what the "restraints" button is for and why it appears locked—will it have a function later on, or something like that?
The restraints are like the tap out button when you are feed with the hose by a feeder,the reason that you cannot tap out is because they need you to grow bigger and that is all you can do when you are at that size,the only way out is to refuse to be fed and hope that you are listened to and then beg to be released and continue to beg until your feeder decides to make you smaller and then you can either buy a matress and go home to grow or be back at the facility and try again,if you gained too much again.I am being vague on what happens when you succesfully beg for the release,in order to not surprise you too much.
You can try to beg,but you dont have anyone and you get to the facility,then you have very slim chances to be released,also the procent increases for every begging performed like 5%->10% and increases until you are released,but resets if you are sent there again.
Hope this helps.
