Walking around the city you fall through our reality and find yourself in a strange place that looks more like an endless string of corridors. You see many doors, but you don’t know which one to open. But you can’t stay here either, so you have to find a way out of the place. Open all the doors one by one – perhaps one of them will lead you home. You also need to restore your level of consciousness from time to time by looking at your wristwatch every 30 minutes. If you don’t do this, you will die.
