This was one of the worst things I have ever had the displeasure of playing. However, beneath it's surface layer lies an intentionally haunting masterpiece.
The expertly and deliberate use of repetitious gameplay, music, and setting cleverly purloins the player of their sense of self and puts them into Aya's reality. You really feel the pain our heroine feels, distressingly chopping her way from one corridor to the next, hoping for the end to be through that next door and end her suffering.

A truly fascinating and overlooked gem.
