About Cult Vacui
Cult Vacui is a point-and-click game with survival horror elements, set in the late 19th century on the remote Scottish island of Barra. You play an unsuspecting janitor hired to maintain the Gladstone family's summer estate. The day before you arrive, a creepy cult performs a gruesome blood ritual on the island's population.
The ritual
Your arrival interrupts the ritual, which can only be completed if every person within the island's perimeter is eliminated. The cult sees you as its last obstacle, or so you believe. With only a few hours before the ritual's final act, you must prepare a strategy to defend yourself and try to survive.
Manage your time
Every action consumes time and advances the countdown to the final act. You choose how to use the limited time available, and can refine your strategy across multiple game sessions. The game includes logical but challenging puzzles and multiple endings based on your choices.
Art and sound
Cult Vacui uses pixel art and has an original soundtrack composed by Ascari, a musician also credited in film. Its average playtime is around 2 hours, though most players finish in about 2–3 hours.
