The Monastery - Version 0.15 by Alcahest

You play as a priest, sent to a convent of nuns to investigate a series of mysterious incidents involving attacks on the nuns when they sleep.
The nuns share the monastery with an order of monks, with a wall keeping them apart to ensure that they all remain celibate. During your stay at the monastery, you may also visit the School for Young Women the nuns are running, and take confessions from people from the nearby town.​
