This is art. I had a one tear while playing last night, but a full on cry thinking about it again this morning. I am blown away by how well this was executed. I thought the spooky person in the mirror at the start might be tacked on to connect to the spooky thing, but I was so wrong. This game was legit spooky and the payoff for the person in the mirror was powerful. Horror rarely has a satisfying conclusion like this, this was masterfully done.
Also, the art and game design were incredible. Few Gameboy games achieve this level of depth and immersion within the extreme limitations of the medium. 11/10, would wash my face again.
