I'm almost offended.
Second question: yes, in the game you are an american spy: and then???
There is a quiz to solve, I don't remember where is it. To solve the quiz you must insert the secret code.
There was supposed to be an image attached to the second question, but nevermind that one. Now the most important point. What does it have to do with liminal spaces?
"liminal spaces" have many meanings.
"Liminal" is originated by the latin word "limen" (=treshold).
If you want, in my game the "war mission" is a trip which trepass the time treshold, back to the past.
Or a trip which trepass the tresholds of european country to live an adventure dream.
