I watched this series a while ago, but I can't remember the name of it. It was an anime style flash, that started in a room and teh guy couldn't leave and he had to make choices of certain objects in the room to help him get out. He reflected on his life and made a decision, and then doors appeared and he had to chose the right door. He ended up in a large circular room with like 20 doors around him. I think as the episodes went on it did the same thing from other peoples perspective. Liek there was one with a black guy in a subway. Soon there was leik 20 people in this room of 20 doors. Any one know what im talking about?
