Voice acting is excellent. Not sure how this guy could communicate with his grandma when she had already passed away.
Game play is exciting because of the elevator. I almost thought I killed the guy by sending him in. About the French speech, j'ai rien compris. :P
After solving this mysterious case, I hope there's more. One room was still locked at grandma's place. Also, the hidden drawing on the ceiling might mean something.
Graphics are perfect as always.
