White Day: A Labyrinth Named School is a South Korean survival-horror game originally developed and published by the studio Sonnori back in 2001. It was remade for mobile phones in 2015 and for Windows and Playstation 4 in 2017.
You play as Skul, the titular hero and meager skeleton, who would be nothing more than a forgettable enemy in most games. Here, though, Skul has been refashioned into a proper hero replete with magical abilities and enchanted items. And revenge against the usual protagonists feels so good.
