About this game
Dear Players,
Welcome to Dunkenwood House—your new school.
You are Arenda Finch. After being expelled from your church-run girls’ school for speaking too many blasphemous words, you have been transferred here. To adjust to your new life, it helps to remember a few rules:
You are not a detective.
Your task is simply to study, repair your relationship with your brother, graduate, and inherit the fortune left to you.
But this manor has a long and intricate history. Strange things happen here, and strange people live here. Conspiracies, crimes, and malevolent individuals may well exist.
You will face choices—some that save you from immediate danger, and others that shape the person you become.
If life at school grows dull, you may look further into the house’s past, your family’s secrets, and the darkness surrounding those you meet.
But the truth never comes without a price.
Good luck.
Your new life begins here.
Our Discord community :
The Demon’s Game
This is not a detective story.
There are conspiracies, crimes, and those who wish you harm.
But when the inhuman intervenes, do not attempt to understand it through human logic.
The Choice Between Life and Death
Some decisions alter your immediate circumstances.
Others shape your future.
All of them matter.
Forbidden Love
To love someone you should not.
To protect the people you care for, or sacrifice them for something greater.
If they truly love you, shouldn't they be willing to give everything—even their lives?
And then—
???
Uncover the concealed truths behind the main narrative and the unspoken secrets of the others around you.
But truth demands payment.
You may have to die more than once.

The English version of the Antonio route is now fully uploaded
The English version of the Antonio route is now fully uploaded. The story is complete and playable through to the ending.The language is still being refined. This update focuses on improving clarity and tone, and I’ll continue polishing the writing going forward. Since the story is set in a British boarding school, accuracy in language and atmosphere matters to me, and I’d rather keep refining it than treat the current version as final.Since May, this project has been developed as a solo project, and decisions and pacing are handled accordingly.If you previously only played the first one or two chapters, I strongly recommend starting a new playthrough. The game is still in Early Access, and earlier builds were made before the endings were implemented. Loading old saves may result in unexpected bugs or issues with reaching certain endings.The Antonio route contains six final endings and nine death endings. There are no “good” or “bad” conclusions. Each one—including the deaths—reveals different aspects of certain characters or events.Which ending you reach depends on earlier choices. Some decisions lead directly to a death ending; others determine which final conclusion becomes possible.These choices gradually shape Arenda’s moral direction. Depending on what you select, she may become more human-driven, more demon-driven, or remain somewhere in between. The ending you reach reflects the person she has become.If you run into problems progressing, can’t reach an ending, or have specific questions, you can DM me here on Discord. I read messages related to concrete issues, even if I can’t always reply immediately.DOMUS AUREARead full article on Community Announcements (Dan)AnnouncementsOfficial
