Amnea28: Two Eternities. Asphyxia

A group of students goes to attend a series of lectures by a respected psychology professor. The goal of the trip was the old hotel "Amnea," which stopped serving its primary functions about ten years ago and now serves as a secluded corner for the professor. A week filled with study did not portend trouble, but with each passing day the atmosphere inexorably changed. Why did the students suddenly begin to behave strangely? What are they hiding? The main character must unravel the secrets of "Amnea," or the walls of the old hotel will not let her leave alive.
