Ruined Factory Escape

This ruined factory area is abandoned and restricted. You have just come to this city and you probably do not know that no one enters the ruined area. Old factories and architectural works have always drawn your interest and so you decide to enter the factory and see what it is like from inside. The moment you stepped inside the factory, the door closed automatically. You immediately realized that there was something very weird about the place. Your focus has now shifted. You will now me looking to find items that you can use to solve some puzzles with the main goal of finding the key that you can use to unlock the door and escape from there.
