Survival VR

You had planned to go on a trip with your friends for an unforgettable vacation. However, you never imagined that a quest for survival would follow. Lightning struck your plane which crashed near a small uninhabited island in the Pacific Ocean. The cockpit's defective transmitter doesn't allow you to pick up the signal to call for help. Who knows how long you will have to wait until rescue teams find you... You are now in shock, scared and hungry. You have no provisions at hand and only the wilderness surrounds you. The weather conditions are deteriorating and you need to find a place to take refuge. Use your critical reasoning to survive. Determine what could be useful on the island in an attempt to stay alive.
