Slowly I wake up, and I find myself locked in a room. I panic, and I know I have to find a way out.
I start exploring the room. When I look around, I see a large door on the east side of the room. I must have entered through that door, but I know there is no way back.
At the west side, the wall was plastered full of propaganda posters with loud slogans. I didn't like it at all.
At the south side, there is a bar. It used to be a lively bar that offered everything from signature drinks to a range of beers and appetizers. But now it's pretty dead. Nothing to see there anymore.
At the north side, there are a bunch of buttons and levers. It looks like they have each a special kind of function, but I have no idea. I shouldn't spend too much time to find out what each of them does—it probably won't help me.
Furthermore, there are 4 doors, one in each corner. The doors are all locked, but surely one of the doors should let you escape! But which one is it? There are some keys here and there, and I think one of them will unlock the right door. However, I can't try the doors at random, cause I have a feeling that one of the doors is really dangerous. Once I open that door, I will be gone forever!
Which door leads to freedom and why?
