Will probably sit down and do a proper post when I can see the pictures but off the top of my head have been thinking as to the nature of the tower complex and the world surrounding it. Two of the many rough ideas that I have come up with so far are:
- The entire game world is actually the internal landscape of someone's unconscious mind (player, patient or enemy). The puzzles, mazes, enemies etc represent different aspects of the mind and provides insights. The tower complex is the key to escaping the unconscious world but is even more tricksome to get through than the outside. Unconscious by the way with respect to the subconscious, not simply knocked out.
- The tower complex is actually a very old umbrella defence system that was activated a long time ago locking the game world away from everyone and everything else. This could be applied to a number of different scenarios. Everything from the shields failing thus hostile intruders entering, to internal decay as a result of radiations formed within the shield etc.
