The Heilwald Loophole

You awaken in a dingy storage room in a pile of rubble and dust. Observing your surroundings you notice a massive hole in the ceiling. How curious. Dazed from the fall and mildy confused you venture into the twisted depths of the Heilwald Klinikum... The Heilwald Loophole takes the classic survival horror trope of being stuck in a run down hospital/asylum and being chased by crazed nurses and doctors but adds an important twist: It is impossible to die. Every action, every decision merely opens up a new pathway to venture down leading you deeper into the Heilwald Klinikum. How far does it go? And what is that god damn loophole about?
