you scoot over to the shady guy and he will undo them for you
To escape from the ropes, scoot your chair over to the shady guy : Point the mouse cursor to the right of your character and drag it back to the left, across the chair. Be careful not to tip the chair over.

Just go the way you got in to get out.
It is unclear what island this is. It may be Red Dragon Island. (Jump onto the logs when they stick out, then jump up quickly.) It may be Super Villain Island. (You can only climb the rocks from the water by going up and to the right.)
