A narrative time-travel game
The Janus Engine
History can be reset. Guilt cannot.
In the 2300s, a scientist receives a completed but flawed machine from their own future self. Each intervention rewrites the past, the present, and the future in ways that are not always clear.
The Engine
One history opens.
Another disappears.
The Engine presents two fractures in history. Entering one closes the other. Every intervention reshapes later centuries, and your archive preserves the choices and consequences that brought the timeline here.
