Dusk Graveyard Escape

He was very close to his grandfather who passed away last year. Today it is the first death anniversary of his grandfather and so he has come to the dusk graveyard to place some flowers on his grave and remember him. After some emotional moments he got up and wanted to leave but he found out that someone had locked him inside the graveyard. Fear ran through his mind and everything around him started to feel spooky. Even the thought of spending the night there would kill him. He must breathe deep and start looking around to find things that would help him get out of the graveyard.
