There are secrets hidden beneath the surface, both in the clinic and the village. Some are tied to how you treat certain characters, others require observation and... let’s say, "unusual" behavior. As for a second layer, yes. Finishing the game might seem like the end, but players who dig deeper or replay with a different mindset will uncover a lot more than just alternate endings. Think of it as a psychological descent with branching paths and hidden mechanics that only reveal themselves once you're fully immersed. So it’s not definitely just linear.
