If you ever wonder "how the fuck did I get stuck like this?", or "I thought I had figured it out... how did it suddenly all go to shits?", or even "I finally got good at this... and now I have to let it go". Every room in our worlds can be reached by finding the key that opens it. The problem is that once we walk in, the key doesn't open the door from the inside. Most often you need to find the opposite key. This can be both frightening and thrilling, depending on how you understand it.
