Minor Update
There were requests to change the background color of either the Maid or the Butler to green in the intermission screen, on the grounds that two grays under the same sky simply cannot coexist.So I decided to settle the matter through a democratic process to determine who would become green.The Butler won, and her background color has been updated to green accordingly.I've attached a recording of the fierce and hard-fought battle.Read full article on Community Announcements (WTFMAN)Patch NotesOfficial
Demo Update - Tutorial Added, Feature Improvements
TutorialThe game will now ask whether you'd like to play the tutorial when starting for the first time. This prompt only appears once. If you're new to the game, I recommend going through the tutorial first. A new tutorial has also been added to show you how to use the clock (located in the upper left of the screen) to skip time.Auto-Move to the Next RoomA new option has been added to the Preferences menu. When enabled, you'll automatically move to the next room upon reaching a certain point in the current room. When disabled, you'll need to click with your mouse to move to the next room.Enjoy the newly updated Slaughterhouse demo, and feel free to leave any questions or suggestions in the Discussions. Thank you!Read full article on Community Announcements (WTFMAN)Patch NotesOfficial
MAJOR UPDATE!!!!!
Chinese (Simplified & Traditional) SupportWishlists from China, Taiwan, and other regions have been climbing recently, so added Chinese language support. That said, this was done using translation tools, and since I have no knowledge of Chinese myself, I can't guarantee the accuracy of the translations. If you spot any mistranslations, please let us know and I'll fix them.Intermission At the end of each day, an intermission will play. The five characters will each advance their own agendas throughout the day, increasing a progress meter. If the meter reaches its maximum, it's game over. (Since the demo only covers one day, the meter will not reach its maximum in the demo.) Talk: Converse with a staff member to increase their affinity toward you. Comfort: Comfort a staff member to reduce their fear level. Persuade: Negotiate with a staff member to recruit them as an accomplice. Reassign: Change a staff member's task to prevent their progress from advancing. The conditions required to negotiate with each staff member differ. In the demo, you can negotiate with one person. Play through and find out who it is. Staff members who become accomplices will no longer find it suspicious if the player is carrying items, and will provide helpful bonuses to the player (not available in the demo). Affinity can be used in certain situations and during negotiations. If a staff member's fear level drops too low, they will flee the house, resulting in a game over.New Time Skip System After reviewing gameplay footage, I noticed many players were aimlessly pacing back and forth in front of doors just to pass the time, so I added a new time skip system. Simply click the clock in the upper left corner of the screen and set the time. You cannot skip to before 9:00 AM or past midnight, and you cannot go back in time. This is not a time machine. The existing activity system, which was originally designed for passing time, is planned to be redesigned as a system for managing affinity and fear...Read full article on Community Announcements (WTFMAN)Patch NotesOfficial

Demo Update - Time to give the Assistant what she deserves!
The mansion has been redesigned. Some areas have a new look, but it won't affect gameplay. Just a general atmosphere refresh.There are flowerpots scattered around the house. Eight of them in total. Not sure who's been tending to them, but either way, she's going to have a busier day ahead.The methanol that was sitting out on the second floor has been moved into a storage cabinet. You shouldn't leave hazardous chemicals just lying around, after all. Oh, and there's a trowel in there too.Two new rooms in the mansion are now accessible: the dressroom and the vault.The dressroom can be entered directly from the bedroom, and the vault is hidden behind a secret door in the library. Rumor has it grandfather stashed some treasures in there... what could they be?Combine the right traps and you can now bring the Assistant to justice.She's the mastermind behind the plot to steal your fortune. So there's no forgiving her, right?Enjoy the newly updated Slaughterhouse demo, and feel free to leave any questions or suggestions in the discussions.Thank you!Read full article on Community Announcements (WTFMAN)
