The cursed monastery

You have been commissioned by the Vatican as an exorcist to set off to an abandoned monastery to save the world from the outbreak of a great misfortune. According to legend, a long time ago an apprentice of this monastery became possessed by a demon after studying an old book "Ritus Morti", who wanted to escape in his new human form. The brotherhood managed to lock the possessed person in the monastery and flee, after some of them lost their minds and died in the process. As soon as you enter the monastery, you will be surrounded by a mysterious force that seals the entrance and traps you. Find and defeat the demon before darkness falls and the demon consumes your soul too. Can you escape before you lose your mind?
