Abandoned Institute Escape

Abandoned institute is the best institute in that place few years ago. This is the strange story about my friend. I went to explore the secret objects to find out my friend who disappeared here few days before. He came here to investigate this abandoned institute. But he did not return. I need to find him. Can anyone help me to find him out and also help me to escape from here. So can you please find out the related objects and solve the puzzles to escape me and my friend from the abandoned institute. Thanks for playing and Good Luck and Have Fun.
