Cursed Home

Horror game
There are three/four doors. Each is opened with a specific key ("Humble" key, for example).
The doors all lead to the same place, a home office.
Each door just affects circumstances.
Instance 1: a normal office with a black cat inside. Everything is just empty and left as if life was interrupted. The main character is turned into a cat off-screen.
Further instances get darker and darker.
The office goes into ruins, there are several identical children, black cats, etc.
The main character makes several attempts to escape, only to be killed as she races down the stairs to the door.
In the final instance, rather than escape the oncoming ghosts (?), the main character stops and accepts them
