Escape From Grease Factory

They're closing down the factory soon. We have to pack our things as soon as possible. It was a good past years, though. You really liked this job... However, it seems fate has something else for you. Your boss asked you to do some extra hours today and fasten up the packing process, so you stayed here alone. You were just about to finish the work for today and leave, but you realized someone forgot about you and took the factory key. The door closes itself automatically and can be only opened with the key. I think the boss has a spare key somewhere...Good luck and have fun!
