-Look for things that can help you

From Create Your Own Story

You look to your right and see a table with some tools on it. You try to reach them and finally after some minutes you get a knife. It fits into the chainlock and with some work you get it open. After some minutes you got your other wrist and your ankles free too. You inspect the room a bit further and realise that there is a locked door and a window shut with planks.

-Try to open the door

-Try to get the planks down the window
