Just Imagine, you are a chemical engineer, you are working in your lab, today you have so many works to do so you are doing your work till night after finishing your work you are going to your home but when you try to open the door of your labs it’s not opening. You are locked inside the lab. It’s too late and no one is there only you are in lab. This big lab is looking scary. You want to escape from there to using hints and some useful objects. Solve the puzzles for opening the doors and escape from there. Good Luck!
