20 Minute

You woke up in a strange, unfamiliar to you room. You wildly beating heart. You do not remember who you are, how and why were here. Only one thought in your head spinning, "20 minutes." What does it mean? Did you have left only 20 minutes to get out of here? And what happens if you do not have time to do it? It is better not to test your luck and just start looking for a way already now.
