Frictionless plane

Out of the nowhere, you fall into an unidentified room and land perfectly on your face when you hit the ground, causing a small nosebleed. You look around and notice that the ground is made of ice??? There are walls that have doors and a ceiling with skylights. The ground is so smooth and slippery. Just pick any of the 4 doors and you might escape. Just 1, but choose your actions CAREFULLY. We don't want to clean up the blood. 🙂
