About this game
Blackthorne’s Manor is a first-person puzzle-horror experience that plunges you into the unsettling depths of a long-abandoned estate.
Your friend vanished after attending a party at the manor, and no one has seen them since. Armed with little more than your wits and a faintly glowing lantern, you step inside, not knowing what you'll find on the other side. Shadowed rooms, cryptic puzzles, and fragments of a dark history wait around every corner. The manor’s decaying halls and strange, unsettling details hint at the sinister events that took place here. Can you uncover the secrets of Blackthorne’s Manor, or will its mysteries remain locked forever?
RISING TENSION
Immerse yourself in the oppressive atmosphere of the manor, where every shadowed hallway and forgotten room hides a story. Interact with objects, solve environmental puzzles, and piece together the chilling history of Blackthorne’s family. Every discovery draws you deeper into the mystery, blending suspense and intrigue in a slow-burn horror experience.
ESCAPING THE UNKNOWN
Move through a semi-linear environment designed like a twisted escape room. Unlock doors, trigger mechanisms, and follow hidden clues to advance. Every puzzle solved reveals more of the manor’s story and brings you closer to finding your missing friend.
FEATURES
First-person exploration with environmental puzzle-solving.
Creepy, atmospheric manor with a story woven into every room.
Inventory-based interactions to manipulate the world and unlock new rooms.
Lore fragments and hidden notes that reveal the manor’s dark past.
Slow-burn suspense that escalates as you uncover the truth.

Christmas Update Branch
For those who missed it, we worked on a christmas update. However, this was a temporary event for the game which we have since removed. We decided to bring it back for those who missed it and was interested as a beta branch which can be accessed in the properties tab. The version is slightly out of date so only check it out if you are interested, I don't believe achievements will work for that playthrough.Thanks for those who are still playing, feel free to provide some insight to more things you guys are interested in and we can try to add them!Read full article on Community Announcements (Kiwivi)AnnouncementsOfficial
Game Achievements Are Here
Time to get achievements!Both by request as well as an interest prior to release we have decided to put some time into implementing achievements. Due to not being required to complete the game and not much documentation we put them on the back foot. However, we are happy to announce we have achievements now! There are 5 achievements and all are gathered by playing through the game, for example entering the manor and finishing the game, the remaining ones are hidden and will be achieved through natural progression. We hope those of you who like to achievement hunt will be interested in checking out our game or going for another run through. There is a possibility we may introduce more both depending on difficulty and how interested you guys are in having more achievements. So if this is something you want to see, like this post and let us know in the comments or flick us a dm on any of our socials and we can research implementing more.Regardless, we thank you for your support and hope you enjoy this update!Read full article on Community Announcements (Kiwivi)Patch NotesOfficial
Blackthorne's Manor Patch #3
We received a report that an extra ethereal potion was in the game, this was part of a system we were originally testing during our vertical slice but must have forgotten to remove. Due to confusion and well it inherently shouldn't have been there in the release build we have removed it. We apologize for any confusion if anyone ran into it (was accessible in the dining room). I will take this time to announce that we are looking into achievements. This may have been known as there was a period while I was testing this feature that you could see them. Unfortunately there were some issues within testing and implementation that is delaying them being added. We will continue to work on getting them set up and hopefully get them into the game (however no promises as documentation for implementing into unity is scarce and those that exist are running into issues due to inconsistencies).We hope you enjoy the minor update and enjoy our game For additional feedback and behind the scene, go join our discord Blackthorne's Manor DiscordRead full article on Community Announcements (Kiwivi)Patch NotesOfficial
Blackthorne's Manor Patch #2
Once again, thank you everyone for playing our game. Due to provided feedback and internal testing we have come with another patch. For now the patches will be slowing down mostly as a. we haven't received really many more issues that we have been able to locate (a couple brought up but non reproducible with details provided) and b. coming into this new year we have been busy with our personal lives and jobs. If you would like to see more patches and updates, make sure to provide information on areas we could improve and things that need fixing and we can see what we can do. VisualRemoved floating aspect of objects in bathtub (Won't include specifics for spoiler) this was as the container wasn't working correctly so the longer you played the less reliable the positioning was which could lead to the objects floating away???? Rather annoying, now they are static but rotate around which was the best fix Rebaked lighting with new changes to provide updated shadows (minor improvement)GameplayMoved the lantern, we had received conflicting feedback for the lantern placement for a long time both pre and post release. Some found it fine and easy to find whereas, other struggled and even stopped playing due to the case. Due to said feedback we felt it was due for some adjustments. We have moved it into the house and near the tutorial prompt which also got removed. This should make it easier to find and you shouldn't get stuck in a dark house without a light which will inhibit your ability to play. This should also reduce the chance players try to grab the wrong lantern. We decided to remove the ability to die, at least for now unless we make some good improvements or get contrary feedback (feel free to let us know if you think this is better or worse). We found players didn't really understand that they could die, it would happen mid game which kinda means you have to restart due to how saving works, and lastly it didn't really provide a positive affect on the experience.

Christmas Update
Christmas UpdateIn the holiday spirit, we have brought a limited time Christmas themed update. This does not contain any major changes to the gameplay nor anything that should overly change the feel of the game. If you have played already, feel free to jump in and check out the new aspects. For those of you not interested in the themed update, don't worry. This update will only be here for a limited time and then will be reverted back to the original experience. Christmas ChangesChristmas tree out by the opening of the manorBaubles littered around the sceneLight snow falling outside Additional ImprovementSlightly changed the text pop up when you create the Ethereal Potion. During development the cooldown was 15 seconds which we changed for balancing improvements. However, we had forgotten to remove the warning which is now fixed. We are still looking further into the upstairs falling into ground bug. We will provide more information if we get a fix!Read full article on Community Announcements (Kiwivi)
