      Game Tips
      
        - When a portal-projectile strikes a wall, a portal is opened.
        - Shooting an existing portal with the other color of portal will close both.
        - If both a blue and orange portal exist, the player teleports from one to the other upon entering either portal.
        - Falling in lava will result in your death.
        - Upon reaching the door, you move on to the next laboratory room.
