Slay Bells is a horror game with first person shooting developed by BMP where you need to deliver the Christmas gift to a friend. However, the way back home is prohibited and you need to take the subway.
From there it becomes a hunt, where Santa Claus appears to bring death and you need to do everything possible to defeat him.
The game is short-lived and you can beat the game in less than 20 minutes. Playstation 1-style graphics serve to bring nostalgia and help in the horror environment.
