Mimic Libray

You're in an ancient library and need to sort books into their
correct shelves, but some of the books are fake — mimics. 
The mimic must be burned last in the fireplace.
The game has two stages. The first is easy, 
the second is more challenging (it's activated after 
the mimic is burned).If you place the mimic on the shelf
or burn the wrong book, the mimic will enter the hunting phase.
The game isn't too scary, since I'm a beginner programmer.
