 The austere settings in the game came about because testers spent too much time trying to complete the puzzles using decorative but non-functional elements.As a result, the setting was minimized to make the usable aspects of the puzzle easier to spot, using the clinical feel of the setting in the film "The Island" as reference.While there were plans for a third area, an office space, to be included after the test chambers and the maintenance areas, the team ran out of time to include it.
