Evaluation
骸心 Mainbody launched on November 6, 2022. At launch, the developer added an exclusive ending to the Steam version, bringing the total from 5 to 6 endings. On January 10, 2025, the developer shipped a substantial content update adding an entirely new third-playthrough storyline, four additional endings, and new CG artwork — representing a significant expansion of the game's narrative content. The developer has made no announcements of further planned content since that January 2025 update, and there are no unreleased DLC entries on the store. The game's store description presents it as a complete short-form experience (1–2 hours), with no mention of ongoing or future additions. With two major content releases in its history and no outstanding commitments or announced future updates, the game appears to have reached its complete form as of the January 2025 update.

Story introduction:
Welcome, new building manager. This room will be your room and office, where you are absolutely safe.
As you know, you are about to work in a disgusting "ghost building", but in fact, few outsiders know that the "ghost building" is actually no ghost inside.
In fact, there is only a group of contaminated "patients" in the building, only some of them look like monsters because of the excessive contamination.
Of course, you do not need to let them recover, as a replacement for the dead building director of the new, your duty is to maintain the normal operation of the building and keep the patients out of the building.
The building manager's primary job is to keep the building in good standing, and a patient exodus would cause people on the outside to turn against our building.
The building has been teetering on the brink of forced demolition in recent years, and it is the building manager's job to protect the building. After signing the agreement the building manager must put the interests of the building as the highest priority and must not leave his or her post without permission.
One, the building manager needs to patrol the building every day and keep an eye on the entrance and exit at all times.
Two, when you see a patient in the hallway, just persuade or drive them back to their room as appropriate, and don't let them out of your sight until they are back in their room.
Third, keep a distance from the patient, do not enter the patient's room, remember.
Fourth, if you encounter an emergency, please return to the building director's office immediately and wait for the patient to return to his room.
Five, if the escape is Beast please stop it at all costs, if necessary the building manager needs to sacrifice himself for the building.
I hope you can last a little longer than the last building manager.
