The professor was known to be an eccentric genius. His greatest achievement was an amazing machine which could immerse one in virtual reality as simple as opening a door and stepping inside. In recent months he worked on the project 100 Doors virtual puzzle. Being a big fan of logical tasks he became obsessed with the development of the puzzle and lost all contact with the outside world. Those who knew the professor feared the worst.
